Glock 17 MOS vs. Glock 45 MOS

[jnc36rcpd]

I intended to order a Glock 17 MOS at my LGS this afternoon, but I had to examine the hot new sexiness of the Glock 45. While I initially thought the full size frame and shortened barrel was goofy, I confess that I actually liked the G-45. I don't think sight radius or barrel length will significantly matter. Any objective reasons to select one pistol or the other? Either weapon will be carried concealed, but I carried my issue 226 and 226R concealed for many years. Thanks and be safe.

[Maca]

I carried a 17 for years, and now carry a 45 but more comfortably in a AIWB tenicor velo holster.

[Whiskey_Bravo]

I have a 19X and a 17 Gen 5 MOS. I previously also owned a 45.

The 17 is my favorite. It balances better with a full size weapon light like an X300U. It is also very fast tracking under recoil and is just an overall joy to shoot. The 19X/45 offers a similarly enjoyable experience but not measurably better to me than the 17. I guess I just like the 17 better. It feels more balanced in an AIWB position to me as well. The longer slide seems to balance the full sized grip better.

[Danjojo]

17 because it is the icon and objectively better performing...unless you personally prefer the more brisk, snappy recoil characteristics of a 19, it's lower weight, or less material bulk iwb/more body and seat clearance while sitting & driving...

I'd only go shorter barrel & slide to get into a smaller grip model but it's all nitpickin' to be honest lol.

45 as a gen4 would have been more interesting to me since gen 3/4 19's didn't fit my hands.

[StraitR]

I went with the 45 MOS to slide swap with a 19.5 non-MOS frame.

No other reasons.

[jnc36rcpd]

Thanks for the input. I'm still undecided between two great choices.

[lwt16]

My duty G45 (non MOS version) has been such a great pistol that my next private purchase will more than likely be a G45 MOS.

I have 2 G17.4s and I've noticed I don't shoot them nearly as much as I used to. I'm also getting excellent accuracy with the G45. My times on several drills are all a tenth or so quicker with the G45. I had no love for this pistol when I heard we were getting them as I had lots of time with my old G17.4 duty pistol. I'm now glad the department went to the 45s.

Regards.

[M2CattleCo]

I've shot both quite a bit and have a strong preference for the 17.

For me it does everything better than a 19, except conceal. Which the 19X/45 doesn't do as well as 17 because the shorter slide with the fullsize grip doesn't tuck/ride close like a 17 does.

I realized all the performance of a compact and all the bulk of a fullsize.

Some cops think it's good for sitting in a car.

[Wayne Dobbs]

Thanks for the input. I'm still undecided between two great choices.

John,

I think the G-45 tracks and shoots flatter. Sight radius, etc. aren't critically affected. I've had a long time association with the G-17 and in fact took one to that Metro Dade training you and I attended about an eon ago! I just think the G-45 has been an improvement on this great standard.

[jnc36rcpd]

Wayne, any experience with the G-17 Gen 5 MOS versus the G-45 MOS? Good grief, life was easier when my employer told me what to carry. Of course, I might have to make that recommendation for the new agency.

My experience with a G19X and a 45 MOS matches Wayne’s. For reference I’ve carried a 17.4 by choice at work for 8 years.

I prefer a full sized grip but I can’t relate the “Brisk snappy recoil” comment re: a G19.

My Agency is currently issuing the P320 in an X carry configuration. We tested compact (G19 size), Carry and full size across a range of shooters. performance on the clock was best with the Carry (G45 size).

[ST911]

I EDC a 19X and shoot a G45, primarily AIWB in a G17 holster from JM. My primary G45 is over 20k rounds now. I'd have to check the book but I think that's still 20k without a stoppage that wasn't induced or expected. Quantifying differences on the timer and target I've found the G45 will have a slight edge on the 17 depending on the shooter. Sight radius difference doesn't materialize and is mitigated by sight choice. Running hard, it is more comparable to a 17 than a 19 but has a flat and fast feel all its own. Balance and function with a WML is good. G45s with RDSs run well but I don't have their data. I've seen some agency/unit transitions from G17/G19 to G45 or G19X as standard, with more planned or pending.

G17s are still GTG and a standard to judge others by, but I won't buy another one. There's no reason to.

[GJM]

In Carry Optics with a dot, I see a pretty even split between the 17 and 34, but have yet to see a G45 with a serious competitor.

[EVP]

I think the differences are minute and will be shooter dependent.

With that said, I like the g45/19x as you can swap slides and gives me the option to have a cut down 19 grip.

You could have 3 pistols that all interchange and would cover pretty much all your needs except maybe a dedicated competition gun.

[LockedBreech]

My work gun is a Glock 19 Gen 5, my home gun is a Glock 17 Gen 5 MOS (well, that one is being vetted still, at this time it's still my 17G4). A local agency just adopted Glock 45 Gen 5 MOS. So I've had time to mess around with all 3 variations in size.

I like the 17 better for full size belt carry or home defense/competition purposes. If I had to spend significant time carrying concealed or sitting in a car, I'd like the Glock 45 better. Both are pretty great.

[Sanch]

Reviving a bit of an old thread:

What if you were carrying with a full size WML X300 in a duty holster? The holster likely is the same for a G45MOS and G17MOS since the light extends past the slide. Would that make any impact to which is preferred?

[jnc36rcpd]

I ended up purchasing a G45 with RMR. I may still get a G17, probably MOS in case I do put a RDS on it. I definitely prefer the full size grip though, since I'm still trying to adjust to the RMR, I'm not sure which weapon I shoot better..

[JSGlock34]

I thing the G45 is the perfect base gun for a Roland Special build. Fits G34 length holsters.

Actually, some duty holsters, made for pistols with WMLs, including the WML-compatible version of the Safariland 6360, have a piece that engages the muzzle, so, a G45 and G17 would use different holster SKUs.

JSGlock34 just posted an obvious example of why one may opt for a G45.

Another factor favoring the G19x/G45 would be the expedited clearing of the holster, during the draw, if the one pistol also served as a concealed carry weapon, in a holster that rides comparatively higher on the body. It may seem to be a minor difference, but many folks have shoulder and/or wrist articulation issues, as they age, or due to injury, and if a G19/G19x/G45 is already at the edge of what is possible, that extra fraction of an inch might matter.

Listen to all of these guys.






I went with the 45 MOS to slide swap with a 19.5 non-MOS frame.

No other reasons.

Personally this is one of the main reasons I went with a g45. That way I have a battery of gen 5s that slides/frames/parts can be swapped back and forth. I vastly prefer g45s full-sized grip but have the option of a g19.

[Rack]

I'm probably overlooking something very obvious but what is the difference between the G45 and G19X? It looks like they are both G17 frames, with a G19 slide?

I've given up hope that we'll ever get a true G19 frame, with a true G17 slide. That's what I've wanted for more than a decade.

Sorry - off topic...

[ST911]

G45- magwell flare, front slide serrations, ships with 17rd mags, black
G19X- front strap toe not compatible with gen5 mag floor plates, straight wall mag well (no gen5 flare), maritime spring cups, ships with 1x 17rd and 2x 19rd mags, coyote brown

[Jason M]

G45 also has the breach face cut opposite the extractor for enhanced extraction and ejection while the 19X does not. This is a big deal for me.

A huge deal.

I was shooting with a buddy that that has 3 19Xs and all three ejected like a popcorn popper.

Did it with full power 147 grain ammo and three very experienced shooters.

[JSGlock34]

Here's hoping the Glock 47, or at least the slide, becomes commercially available.

[M2CattleCo]

Why??

The whole reason the 17 shoots softer than the 19 is the recoil spring with more coils.

[JSGlock34]

Why??

The whole reason the 17 shoots softer than the 19 is the recoil spring with more coils.

For those who want to pair the longer slide with the shorter frame, it is the only option that is actually in production, if not commercially available.

[TCB]

Why??

The whole reason the 17 shoots softer than the 19 is the recoil spring with more coils.

My 47 shoots softer than my 17 & 19…pretty close to my 45 but haven’t put those side by side yet.

[M2CattleCo]

Let me guess.

It’s a totally different gun and you have to shoot one to believe how incredibly soft and flat it shoots.

Amirite?

[TCB]

Nope. It’s just a run of the mill Glock that shoots more like a G45 than a G17…which is a bit softer. It’s subtle, unlike the attitude in your post.

[M2CattleCo]

My attitude is what it is because a 45 is a functionally a 19 and 19s don’t shoot softer than 17s.

[john c]

My attitude is what it is because a 45 is a functionally a 19 and 19s don’t shoot softer than 17s.

I disagree. With the longer grip of the 45, I get more leverage on the gun to counteract the torque on the gun during slide travel, compared to a 19. I have pretty big hands and my pinkie rests on the magazine floor plate when shooting a 19, so my grip on the 45 is much better.

So I disagree that the whole package is like a 19; the top end is, but that’s it.

I vastly prefer the 45 over my 19 or 17.

Recoil is what it is. You may think a 45 is softer than a 17, but it’s not.

[HeavyDuty]

Recoil is what it is. You may think a 45 is softer than a 17, but it’s not.

Not a physicist, but leverage would be different between the two due to dwell time differences. And if he believes it is softer shooting for him, who am I to say differently?

[john c]

To clarify, I don't think the 45 is softer shooting than the 17, it just tracks flatter and returns to the target faster. I disagree with your comment that it's just like a 19.

However, I do respect M2's position.

[GJM]

I am not sure softer is an attribute we should be striving for in a handgun.

Softer is better. More accurate, faster, and more reliable.

[ST911]

I'm not sure "softer" is the right word, but it's close and more universally understood. It's also the most frequently heard word with those transitioning from G17.

[stomridertx]

Count me in the group that thinks the G45 is the best gun Glock has ever put into production.

[vandal]

Had another outing with my G45 MOS + RMR + PMM JTTC Ultra 2-port Comp today. It's like a magic gun. Laser beam + flat. I did have to switch to a Gen 3 15lb recoil spring setup which bothered me conceptually, but it sure shoots good!

[GJM]

I have been tricked enough by feelings that I rely more on the timer.

A great feature of the 45, is being able to make it into a 19 with a grip change, as I did this morning when I wanted less printing.

This is overlooked I think. G19/G45 is a great combination.

Do you notice a difference in recoil with the 19 grip?

[GJM]

Do you notice a difference in recoil with the 19 grip?

A 17 length grip definitely draws and reloads better for me than a 19 with a 19 magazine in it. I can also get more meat on the grip with a full size grip, although a full size magazine in a 19 helps with that.

[M2CattleCo]

Same here. I greatly prefer the full size grip, but I don’t notice any difference in recoil control or felt recoil between the two.

[Wonder9]

Gen1-4 = G17
Gen5 = G45

Curious if there were more data points or opinions on the g17/47 vs 45?

[JTQ]

I'm also a bit interested, as it seemed with optics, "the folks" were all choosing the shorter slide guns.

A few months back, doing some YouTube watching, I ran into some Ben Stoeger videos and noticed he was now shooting Glock's.

It looks like his entry into the Glock world was the G17, but then when he decided to go with an optic, he moved to the G34.

Anyone know the issue with recoil springs? His video is the first I'm hearing about it. Has it been resolved?

[spyderco monkey]

Curious if there were more data points or opinions on the g17/47 vs 45?

One of the more interesting data points to me is how similar the G17 and G45 are in weight (weights listed on Glock website):

G17 MOS: 625g
G45 MOS: 616g

That's a difference of only 9 grams; a fraction of the weight difference between mounting a RDS vs Irons. I'd be very surprised if this small reduction in reciprocating mass is impacting recoil impulse.

For those with a G45 and a 17 MOS, could you weigh the respective slides without barrels to see what the actual difference is in reciprocating mass?

This would also help to see if the weights published by Glock are accurate.

Years ago, I swapped the same trigger group between a G34, a G17, and a G19. I got the best scores with the G19.

I have a G45 right now due to being able to getting from the factory milled for an ACRO.

I much prefer the recoil impulse of the shorter slide. However, if I could get a factory milled G19, I go that route.

***I'm aware that I can put a 45 slide on a 19 frame.

I suspect the difference in slide length is more significant than slide weight.

[Super77]

Something to consider: If you add a compensator like the one PMM makes to a G45, it will git in G34 holsters. Same comp on a G17 is too long for most holsters.

[vandal]

Radian comp on a G45 fits in G17 holsters FWIW.

This may sound a bit strange but I'd wager that it has a bit to do with the 147 gr. ammo. 'Full Power' means little to me, what do you mean by this? As in, not watered down powder puff stuff? Even if it's something like a warmer HST/GD load in 147 the reality is that the actual pressures of those rounds can be a good bit lower than 115/124 gr. stuff in the HST/GD spectrum.

The Glock design in 9mm is designed to handle very high pressure ammo without problems so the fact that you're seeing issues is not surprising at all to me personally. Now, if you were feeding it something like the M1152 ammo at 115 gr x 1300 fps loading and having the same weak ejection.... I'd say you got a crap gun.

The pistol should be ejecting well over 6 ft. away from the shooter, if it's not then your recoil spring is too strong in relationship to your ammo. Try +P+ or +P in the lower bullet weights and I'd expect it to run like a sewing machine all day long. Experienced shooters or not, a single load/bullet weight causing problems in a pistol is not indicative of a bad design at all IMO.

This reminds me of people buying a Geissele AR and then complaining that it doesn't run on garbage and/or weak sauce ammo...

I would wager it is because the 19X pistols don't have the breach face cut that the forward serration Gen 5 pistols have.

[RealSelf]

I would wager it is because the 19X pistols don't have the breach face cut that the forward serration Gen 5 pistols have.

Certainly the cut would likely help but has anybody with a 'problem' pistol actually attempted what I am saying here? Does your 19X do this with 147 gr ammo that is on the warmer side or did it ever?

[SWAT Lt.]

Why would someone want to mess around with recoil spring weights or run +P or +P+ ammo for training? Who wants to go through the expense and frustration, not to mention the increase in recoil and wear?

GJM is right, it is the Gen 5 breach face cut that greatly enhances the ejection of brass and is one of the reasons I only own Gen 5 guns, with the exception of my old duty gun, now. Gen 5s eject strongly even with regular old ammo (including on the last round) and, if one were concerned about weak and erratic ejection, purchasing one of those would be the easy fix. I have not looked closely at a brand new 19X in about a year or so, but at that time they still did not have the cut. IME more powerful ammo will increase slightly the distance the brass is ejected (in 9mm, 3rd Gen .40s clear it out pretty well anyway) but does not necessarily fix the erratic ejection pattern, especially on the last round. I always carried +P ammo in my earlier generation Glocks for that reason.

Why not change recoil springs for training? What is the big deal? I am not advocating using high pressure ammo for training but simply noting that when pistols are designed around high pressure ammo then one should not be surprised if it's less than stellar with lower pressure ammo. I am also not suggesting that the breech face cut isn't a positive feature but simply that you can expect better results just by switching ammo or tuning a recoil spring to your chosen load. The easiest thing to change is ammo but recoil spring changes are now a breeze with something like the Radian Compressor system for the G19 uppers.

Again, many people erroneously assume that heavy weight bullets mean 'hot loads' and the reality is that this actually allows for less powder capacity in the cartridge (therefore often loaded to lower pressures because of this). Can you also please clarify what exactly you are regarding as 'more powerful ammo'? If not specifically naming known loads then it's not a very helpful data point. Also related, as another person posted the Apex FRE extractor has been known to fix this type of ejection pattern problem via the claw holding onto the spent case more positively to keep it in the correct position when it hits the ejector.

[M2CattleCo]

It’s amazing how people make excuses for Glock pitching hot brass in their face.

Worse than the 1911 guys..

Knock yourself out, bro. Change all the springs and extractors you want. If that does fix the issue, and I say if, then how much time and money have you invested in a gun that still has a couple of other areas of concern? My experience may pale in comparison to yours, but I was one of the armorers for a 1300 officer agency that issued Glocks for the last 14 years of my career. I have seen and experienced issues with the Gen 3/4 guns that made me personally switch to all Gen 5 guns (with the breach face cut).

Sorry, I thought it was clear enough, but the more powerful ammo I referenced was the +P and +P+ ammo I mentioned in the first sentence of my post and that you had previously recommended as a fix.

Again, I'm not an apologist for Glock at all and actually went away from them many years ago when I started having BTF over a decade ago and sent the guns back and got zero improvement despite them swapping out parts. I am comfortable swapping extractors/ejectors/RSA on Glock Gen 3/4 systems so it's really no big deal here and that is one of the biggest reasons to use a Glock is the ease of working on pistols yourself if you don't have an armorer.

I am curious what the most common issues you saw from 3/4 generation pistols in that role. How far away would you say the brass was ejecting with +P and stronger ammo? As in dribbling out at your feet or maybe a few feet away but not in a consistent landing spot or direction? The ones I had (gen 3/4 17's) definitely had BTF but they were reliable given something in the neighborhood of 124 Gr. Nato power levels of ammo.

Tell me you didn't try any high pressure ammo in a pistol designed for high pressure ammo without telling me you didn't... :rolleyes:


Tell me you don’t understand why they do that without telling me you don’t understand..
