Glock Extended Magazine Release-And Why I Switched Mine Back To The OEM One

[JonInWA]

Several years ago, a great friend of mine provided me with two Glock Extended Magazine releases for my Gen 3 G17 and G19. What I really wanted was the FBI one; AKA the Magazine Release Glock Allegedly Kiped From Larry Vickers (whether or not that's actually true, I don't know). However, those at the time I was in the hunt was pretty much unobtanium, so I went with the full-blown Glock Extended.

Mechanically, they worked just fine, and provided me with some nice stand-off distance from the receiver for my releasing finger to make it easiier to access and activate; and they're relatively sharp corners really didn't bother or affect me at all.

However, there were two downsides; 1), if you placed the gun release-side down on a flat, ungiving surface (like a nightstand table top) and inadvertantly pushed down, youi'd trigger the release; 2), Similarly, if you holstered the Glock with the Extended Release in a high-wall holster, where the release-side holster wall impacted on the release extension, it could inadvertantly activate the magazine release, and you'd be unknowingly have a single-shot pistol.

Obviously, there were some practical work-arounds: For nightstand use, I avoided the issue simply by propping the slide on an immovable raised object on the nightstand, which both pre-positioned the Glock for easier grabbing and kept the extended release out of trouble. And for carry, I simply judiciously chose appropriate holsters, ones that had cut-outs or no material around the magazinew release area that could impact on the magazine release.

However, I inevitably rigged up one day with a non-compliant holster, one that I am T&Eing. And I strolled out EDC'd. And when I got home, I discovered that the holster/release impact had indeed activated the release. The magazine was fractionally disengaged from the retaining catch-lowering the magazine sufficiently to preclude the slide feeder rail from stripping out and chambering cartridges from the magazine-and I was noncholantly strolling around with a single-shot pistol...

And while I liked the stand-off distance provided by the extended release, I literally can't recall a time where I fumbled to access or had any difficulties in activating the OEM release. It may take a slightly more forceful/deliberate effort, but that's simply not a big deal, and effort that I normally expend anyhow when activating a magazine release.

So-back to the OEM release on both the G17 and G19. And unless I choose or convert all my appropriate Glock holsters so that they can't inadvertantly impact on a magazine release, prudence dictated that where I'm at is where I'll stay (unless I dedicate any gun to being specifically a game gun, with a specific game holster-which I certainly don't see happening with the Glocks concerned.

So, not that the extended release is a Bad Thing per se, or that they (in my case, the Glock component) don't work and work effectively. But for me, they turned out to be not the best idea. YMMV. And I realize that if I really want a quality intermediate-length extended magazine release for my Glocks, there's the Vickers one, which my understanding is the same size as the FBI component; an intermediate between the Glock OEM and Extended length, with less chance of inadvertant release, but going that route would cast me out of SSP into ESP in IDPA. Not exactly the end of life as we know it, but for the time being I'll just stick with the Glock original component

For various reasons I've always kept my guns stock. Every. Last. One.

The advice to stick with an unmodified Glock is a safe bet. That said, I think that a person with a Gen3 should at least consider trying the Grip Force Adapter. Similarly, the advice to stick with the standard (short) OEM magazine release is a safe bet, and with an unmodified Gen3, it's what I'd do. With a Gen3 equipped with a Grip Force Adapter, however, I think a person ought to at least consider trying the Tangodown Vickers part.

I've gone back to stock on all of mine as well. Not sure if anyone else has run into this but, the gen4 and gen5 release obviously encroaches closer towards your support hand. If your support hand grip is remotely aggressive and rotated forward, you end up all kinds of surrounding the g4/g5 mag release. Too close for my comfort, but I've also been known to worry about "things that don't matter", so YMMV. ;)

On my stock gen 5, I slightly rounded off the sharp corner near the trigger guard.

I think it's something to be aware of, imho.

[GJM]

The Gen 3 OEM extended release sticks out quite a bit. Bill Rodgers first showed me how he removed material to make them smaller.

The Gen 4/5 OEM is only marginally larger than stock. I believe that it was developed for the Feds. It does seem enough bigger to create issues with holsters or lying on a flat surface.

USPSA competitors with large paddle style mag releases, commonly place the pistol down on a surface with the mag release up.

[WDR]

The only gun I've ever had pop a magazine out on me, was a Kel-Tec P-32. Carried in the right front pocket, the mag release wouldn't get bumped. If I tried to carry it in my "off" (left) side front pocket, with the mag catch facing outwards, invariably I'd push/bump/squish up against something that would depress the catch far enough to release the magazine. My solution was to take a small file to the plastic button, round it off and reduce the length enough that it no longer was able to be pressed when carrying on my off side front pocket. This took a bit of trial and error, taking a smidge off at a time and trying it for a few days. These days, my pocket gun is a J-frame, and the P-32's have gone on down the road.

I can see how the longer Gen3 Glock catch could cause issues, but I never had any when I used them. When I used them, the holsters I used were molded to accommodate and protect the longer catch. Cutting down an extended catch to something in the middle, size wise, seemed to work best for me. The Gen4/5 "FBI" catch doesn't seem long enough to interfere or cause any issues at all for me... even laid flat on a nightstand or table top. I think the more rounded front edge is less likely to get bumped off, verses the more square standard catch, but that is strictly my opinion/conjecture. The extra length is minimal... a millimeter? Far less difference than the Gen3 parts, in any event. I swap the "FBI" catch into all my Gen5 guns now.

[rdtompki]

I'm looking at Wilson for my Staccato C. The extension can be removed for EDC. I lead a low speed life so 9+1 should do fine although I'm training myself to carry an extra mag.

[MGW]

My grip causes magazines to inadvertently drop out of lots of pistols. During quals a couple of weeks ago I dumped a magazine out of an M17 after the very first round. I rarely do it with a stock Gen 4 or 5 Glock but it can still happen. The only pistol I don’t remember it happening with is a stock Gen 3 or any Gen of the 21. Never happened with a 1911 either. Extended releases are a big no for me. It’s one of the things I love about an HK paddle release. I know there’s no way for my grip to accidentally release it.

I thought about installing OEM extended magazine releases on my Glocks but noted the same thing. I have short fingers but meaty palms and I didn't want to risk activating a mag release when I don't mean to.

[vcdgrips]

My work around to the real issues ID'ed by the OP (on a brace of G34s and G35s) is to simply remove some material from the OEM Gen 1-3 extended.

While it is easier to be more uniform/precise removing said material with the mag release uninstalled from the pistol, one can do a serviceable job with the mag release in place.

For that application, my "tool" of choice is a 2 or 4 way emery board and just go slow.

I have no experience with any Gen 4/5 units.

[M2CattleCo]

Yep.

[HeavyDuty]

I rather like the Gen4/5 extended and have it on all of mine. It really isn't more proud than the stock at all, and I've never had issues with uncommanded releases. Are these similar to the ones people upthread referred to as the "FBI" version?

I started using the Vickers releases on my slimlines.

[blues]

I disengaged the OEM standard release on the Gen 5 G26 once or twice.

[HeavyDuty]

I have a problem with the square front on the OEM Gen5 - I can see that happening.

[blues]

I have a problem with the square front on the OEM Gen5 - I can see that happening.

I think it was when I had the 12 round OEM loaded in the gun. Tighter fit, with more tension on the spring.

[CHNEAL]

I ran both the TD/Vickers mag release and slide stop for years on several Gen 4 19’s without issue. Tens of thousands or rounds and draws. In ‘17 I had to have my left (support hand) wrist rebuilt after an accident. Had to relearn my grip, press-out and hold with a wrist that only has 25% movement and wont roll forward. Started dumping mags and stoping/inducing slide locks…been stock Glock ever since.

[Nephrology]

The Gen 3 OEM extended release sticks out quite a bit. Bill Rodgers first showed me how he removed material to make them smaller.

I kinda McGuyvered' that one on my own right around when I first registered here probably. I just took a set of files and took them down until I could turn the gun over with an empty mag inserted and push down on the gun against a table without ejecting the mag. They end up more or less Vickers sized. Still use them on a bunch of my guns today.

[Bergeron]

I use the Vickers on my 19.4s, and I've never had holster/grip/laying on side unintentional releases. I also shoot right-handed, but have the releases set up for use by my trigger finger, so that may play into the issue.

[Screwball]

I put the extended magazine and slide release on my retro P80… prefer it due to having larger hands.

Never had an accidental magazine release.

[JonInWA]

I like the Glock extended slide release-I've got it on all on mine too.

Best, Jon

[willie]

My early Sig's stamped with other brand names had heel releases as did my P-38's. Always I have preferred them. I have had a couple custom holsters dump 1911 mags.

[HCM]

Ran a stock Glock 17 gen 4 for 8 years - no issues with the stock mag release.

I've run or participated in training for hundreds of LEOs with gen 3, 4, and 5/M Glock 17, 19, 26 and I've never seen a mag dump inadvertently with stock mag releases on any of them.

I have seen mags dumped inadvertently a few times from stock SIG P365/ 365 XLs and multiple by a shooter using a Staccato P Duo in a recent class.

Re the Glock Extended slide lock - I despise it. I've both experienced and seen it induce malfunctions by locking the slide with rounds remaining in the magazine. I've seen this occur with both large handed shooters such as myself and small handed shooters so it seems to be related to grip rather than hand size.

[TCB]

I have the OEM extended releases on all my Glocks (all Gen 5), just placed one of them on a hard flat surface and pressed down hard, wiggled it around every which way to try and get the magazine to release with and without a X300U on it and…nothing. In the Safariland holster I use at work I’ve fallen on the gun, rolled around on the ground with it and smashed it on block walls while climbing over them and never had a magazine pop out. I have Wilson extended magazine releases on all my 1911 that I’ve used extensively in USPSA and on table starts I lay the gun magazine release down and have never had it release a magazine…is this something that happens often to you guys?

The issue with Glock extended magazine releases is regarding the extended release Glock makes for Gen 1-3 Glocks; Gen4 and Gen5 releases (in general, and also regarding the extended ones for them) have less protrusiveness.

[RAM Engineer]

Never seen any downsides to a Tango Down/Vickers release in Gen3, Gen4-5, or slimline Glocks. A marked improvement over the stock releases.

A previously reported downside to the Vickers/Tango Down slide releases had to do with weak or defective springs on them; I don't know if it's been substantiated or resolved.

I've been perfectly content with the Glock extended slide stop/release component, but I've heard of others having ergonomic issues with it, and/or experiencing premature slide lockback with it due to hand size/grip positioning.

Mine have been used without issue on all my Glocks from 2003 forward.

I have an old thumb injury, and a stock Glock slide release hurts like hell. I’ve been using the Glock extendeds for years, but started trying the Vickers ones - the extra with makes it just doable. I still have the Glock ones in case the Vickers ones shit the bed.

Sorry, I was referring to the Tango Down Mag releases. I only use OEM slide releases.

After a few years of hearing how the Vickers mag release was a must have I put them on a few guns - G26, G19, G17. Soon on the two smaller guns I found myself leaving seated positions with a released magazine and took them off and returned to OEM. Problem solved. On the 17 it never occurred. I theorized the geometry etc of the full size grip may effect some sort of clearance for it. Never have seen an issue with the G19X or G45 OEM either.

Lesson learned. I never struggled with hitting the OEM part on those guns and resolved to leave that shit alone.

[OlongJohnson]

I guess this thread would be another reason to try a Gen5 if prices ever get back to pre-dempanic normal.

Some time back, I read of the "flat surface test" and tried it on some stuff. Put all flavors of B92 extended mag catch I had up for sale. I'm blessed with long fingers and the stock one works fine for me.

[WDR]

For shits and giggles, I just unholstered my 19.5 MOS/RMR/TLR7 which has the Glock OEM extended "FBI" (SP08794) catch in it, laid it on our (very sturdy) kitchen table pointing in a safe direction, then put my full body weight straight down on the gun with an open palm... All I accomplished was lifting my feet off the floor for a second, while I shifted weight a little in different directions trying to replicate the mag release/table issue. No dice. Magazine stayed secure, and I could feel zero give. I don't think it's depressing at all, between the "thumb rest" molded into the grip, the extended Gen5 magwell flare, and the flat body of the TLR7 being basically the exact width of the frame. There just isn't any give.

I'll try it again later without the TLR installed, and see what happens, but I'm guessing there wont be a difference. Not scientific, single result, don't take my word for it, etc.

I am however, 100% sure my Gen3 19 with the long OEM catch would fail this test. It is visibly long enough to protrude beyond everything else on the side of the gun.

I've had a couple Gen 3 extended releases that I sanded down and stippled. They're pretty long.

OTOH I've got a couple Hyves which I really like, and the length is somewhere between "regular" and extended. I really like those, but the downside is the aluminum chews up mags much more noticeably than polymer. Not enough for the average joe to care about, but if you're practicing reloads fairly often you'll see the notches on the mags start to curl.

[JonInWA]

I recently used the G17 as a test bed for a Chinese RDS for an Amazon review; the RDS (a Monstrum Raven SRS, for any interested) was a steaming pile of junk; my first onde failed shortly after installation, and the replacement they sent me survived through a 10-15 round zeroing session, and then totally failed 2 rounds into a subsequent range verification and practice session. The RDS was interesting in that it mounted on a plate that utilized the Glock's rear sight dovetail, potentially a boon for owners of earlier non-MOS Glocks who wanted to dip their toes in the RDS rabbit hole without the additional slide milling expenditure.

The Monstrum mounting plate was decent, fitting tightly in the dovetail, and further secured with grubscrews. But due to the repeated RDS failures, I went back to the original sight configuration I'd chosen back in 2006/2007, Glock steel sights.

I've become a huge fan of the Hogue HandAll Beavertail grip for Glocks. Unlike the previous HandAll sleeve, these are MUCH more tightly molded, with skus for the various Glock generations and frame sizes. I've had excellent results with them, and have them mounted on my Gen 3 G17, Gen 3 G21 and Gen4 G22/G31. They provide an excellent grip interface and a very natural aim point on draw. With the Hogue installed, I decided to re-examine the viability of the Glock extended magazine release. Previously, I'd found that if the G17 was placed magazine release side down on a hard surface, it protruded far enough away from the frame to be easily inadvertently activated if you pushed down on the gun (say on a nightstand) when acquiring it, releasing the magazine, and giving you a 1 shot defensive weapon....generally not a Good Thing.

https://i.imgur.com/H8l8Ctah.jpg

However, I find that with the Hogue grip installed, its just protrusive enough to give enough stand-off space between the release and the hard surface that the gun is placed on: Score-one problem area concern neatly removed.

https://i.imgur.com/4THmFC5h.jpg

https://i.imgur.com/1BL24W1h.jpg

This makes it much more viable, as I find that the extended release provides a significantly increase in quick magazine release accessibility and activation. However, if the extended release is installed, make sure that you check with all of your holsters, as a release-side holster wall will impinge on the extended release, activating it with very little effort. Since most of my carry and duty holsters wall's don't impinge on the magazine release (normally there's a holster cut-out that eliminates potential magazine release and holster side interaction). The great news here is that the grip is cost is extremely low, and it's a very high quality piece of kit.

So, there you have it; JonInWA again flipflopping on aftermarket holster viability. But this time, I think the grip is on to stay (and as the grip is, it stands for a viable, all-weather improved grip alternative). The grip comes from Hogue in multiple colors-you.re on your own there. I prefer the Hogue HandALL to other available alternatives; it replaced a portion of a rubber inner tube (great for the gamers amongst). And it's bulged in just the right place for user ergonomics, and it provides me with a comfortable carry option.

A surprisingly viable inexpensive (i.e.: dirt cheap-$14 'Murrican...) is the Glock Sport/Combat OWB belt holster. Made of flexible polymer, I've had several for 20+ years. They're customizable via an X-Acto knife in two areas: 1) For belt widths, buy removing the horizontal dividers inside the belt loop wings as appropriate for your belt width, and 2) by removing the shielding wall where the magazine release lever is housed when inserted in the holster.

Removing the shielding wall is essential if your elect to use an extended magazine release lever, as pressure from the wall can impinge against the lever and inadvertently trigger the magazine release, slightly lowering the magazine in the gun, leaving you with essentially a 1 shot Glock....generally not considered to be a Good Thing.

Simply cutting away the wall where the magazine lever is housed quickly removes this concern. I cut mine to accommodate both the earlier Gen 1- 3 releases, and the later Gen4 and 5 release levers. It's easy to do, and does not in the least effect the operability of this simple, but exceptionally useful OWB holster. I simply put the gun in the Sport/Combat holster, lightly scribe a line where I need to remove the wall material, remove the gun, and cut with the X-Acto knife (or similar). It's a quick job: I first cut for the earlier Generation release levers, and then re-cut (additionally cut) for the Gen4/Gen5 levers.

After the cut, the magazine release lever is flush with, but does not protrude beyond the surrounding holster wall, so pressing the holstered Glock against your torso or clothing does not impinge against and trigger the release. Here's a link showing how it works and looks with the various generations of Glock extended magazine release levers:
