View Full Version : D&L/Cominolli Glock Safety

As previously noted, I have long preferred having a manual safety on my pistol, as I have twice seen officers' lives potentially saved when another person gained control of an officer's pistol, but the engaged manual safety prevented the weapon from firing --I don't like to think about the outcome if the pistols involved had been a Glock, Sig, XD, revolver, etc.... In the incidents I have witnessed the officers had NO way to mitigate the threat prior to losing the pistol, despite adequate training and good quality Safariland retention holsters. All the DT/retention techniques in the world do not help when an officer is on the ground unconscious/semi-conscious. A manual safety can give officers a brief respite to neutralize the suspect using disarming techniques, access back-up weapons, and allow cover officers the opportunity to react and engage.

I have also seen several Glocks inadvertently fire when a piece of equipment inadvertently depressed the trigger, despite the shooter’s finger being outside of the trigger guard, straight against the frame--an engaged manual safety would have prevented these accidents.

In addition, for those carrying pistols AIWB, a manual safety is a prudent precaution.

The availability of an ergonomic manual safety is one of the main advantages of the M&P over Glock--so much so that I frequently contemplate dropping Glocks and going exclusively to M&P's w/ambi safeties.

Given the above, I have always been interested in the Cominolli Glock safety (http://www.cominolli.com/), but did not like the poor ergonomics...until now. Former LE officer and current noted gunsmith Dave Lauck of D&L Sports in Chino AZ (http://www.dlsports.com/) has developed a modified safety lever for Cominolli equipped Glocks that has much better ergonomics, similar to a 1911. We decided to give them a try, as shown below:

Keep in mind that the Cominolli safety does NOT work for left handed shooting, as there is only a safety lever for the right thumb.

The D&L Cominolli safety lever works in the same direction as that on the 1911 or M&P—up is on, down is off to allow firing:

http://i1292.photobucket.com/albums/b580/DocGKR2/Safetypositions_zpsa09d3551.jpg

Dave recommends using the Ghost forward bullet slide release ( http://www.ghostinc.com/product/GHO_BFS_BLK/Ghost-Bullet-Forward-Slide-Release-Combat-Black.html) with his enhanced Cominolli safety lever, as shown below:

http://i1292.photobucket.com/albums/b580/DocGKR2/DLSafetyandGhostRelease_zpse853079c.jpg

The Ghost Glock forward slide release is positioned in about the same location as safety levers on 1911’s and has proven to work very well—so much so that I’ve now installed them on several other standard Glocks without the Cominolli safety.

The D&L safety equipped Glocks did not pose any problems fitting into a wide variety of holsters, including the superb Safariland 6354DO ALS duty holster.

http://i1292.photobucket.com/albums/b580/DocGKR2/DLsafeyin6354DO_zpscede631d.jpg

A couple of tight fitting kydex CCW holsters required some minor trimming or gentle heating and re-shaping, but this was easily accomplished.

While at D&L, Dave also installed his stainless steel G17 barrel with sand cuts ( http://www.dlsports.com/custom-sand-cut-glock-pistol-barrels.html):

http://i1292.photobucket.com/albums/b580/DocGKR2/Barrelgrooves_zpsbbbfc8d1.jpg

Dave believes that the flutes give dirt and grit somewhere to migrate to, instead of grinding between the barrel hood and the inside of the slide, allowing pistols to run smoother and longer when used in dirty conditions.

Initially I was a bit slower getting my first shot off, but as I’ve got used to the D&L safety equipped Glock over a few thousand rounds, my times are getting back to normal on standardized tests like the 10-8, FAST, LAPD SWAT qual, 99 drill, etc... Accuracy was not effected in any way by the addition of the safety. Each of these D&L safety equipped Glocks has now fired over 2000 malfunction free rounds without any cleaning.

I am not suggesting anyone modify their Glocks; I am stating that having used a variety of pistols on military and LE duty, as well as for CCW over the past 30 years, I now strongly prefer pistols with a manual safety based on my direct experiences with both types. The D&L/Cominolli safety equipped Glocks are an option that appear to work well. Other individuals will have disparate experiences and will make different choices.

I've got other priorities right now but I'd be interested in cost and turn-around. The website doesn't give any details.

I've always shot Glocks and it would be nice to have some time with a manual safety. Might push me over to carry appendix.

DocGKR,

Thank you for your contributions on this and other forums.

Slightly deviating from topic; Do you feel that having a manual safety should be of the same level of concern for non-LEOs or those who don't open carry?

DocGKR
06-15-2013, 06:03 PM
Cost was $250 or so, turn around was less than a week.

I like having a manual safety on any pistol, whether for uniformed open carry or CCW, although it is perhaps a bit less critical for concealed carry.

Imagine being mugged, hit over the head, and stunned; bad guy pulls out your pistol, but does not remove safety and so pistol fails to go off as he sits there squeezing the trigger...I personally saw this happen to someone.

You are at home and set your pistol down for a brief moment as you begin to change and your child who was hiding reaches up and grabs it....I personally have seen this occur once as well.

You are carrying IWB and your jacket zipper catches on the trigger as your attention wonders a brief second while re-holstering after a stressful encounter--boom...I have seen this happen to someone as well. This can be particularly tragic with AIWB...

$250 was both barrel and safety?

How does the thumb safety work with a Vogel-ish grip? Not sure if these are your pistols, but I thought you had removed the GFA -- something change?

DocGKR
06-15-2013, 06:24 PM
Vogel grip works fine.

I have not been using the GFA; however shooting a lot this week to test the safety levers, I managed to take a big chunk of flesh out of the web of my hand--typical Glock slide trauma, so I put the GFA back on to protect my hand. I really prefer the M&P ergonomics to Glock...

Note that Glock has a factory manual safety available and has sold it to some large LE agencies; the D&L version seems to be more ergonomic than the Glock OEM version:

After 35yrs of 1911, I bought a Glock 36. I assume most readers of this list already understand that particular choice. Like (most) 1911 owners, I like the thumb safety, and like the idea of such a safety on a Glock pistol. I appreciate this thread and the many knowledgeable remarks. Questions: Is this available for Glock 36? Is it available as a parts kit? And what the heck is the distinction re 3-pin?

I realize the G36 may be a pistol with limitations. Just curious whether it is a prodigal pistol with limitations. Thanks in advance for suggestions and observations. I am new on this list, and glad to be here.

No clue if it works on a G36--you'll need to call D&L.

Personally, if I were a 1911 shooter, I'd go with an M&P45 w/ambi-safety or maybe an HK45c any day over a G30 or G36...

How are the ergonomics of this safety vs those of the M&P safety?

How positive is the engagement of the safety? ( if that makes sense)

I have an M&P 45 with a TS and while it works ok, it does not allow me to use my normal grip or a very comfortable grip.

I also have a G19 that I would be interested in putting a safety on.

Thanks for pointing this information out and sharing your experiences with us.

DocGKR

The safety is quite positive.

I prefer the M&P safety; in fact, I have come to prefer the M&P safety even over 1911's.

The only downside is that is only works for right hand shooters...

TheNewbie

Thank you for the response.

What is about the M&P safety that you prefer?

I had M&P 9mm that I ran very well at one point, and I may just need to go back to all 9mm. I shoot it so much better.

I am strongly considering sending my Glock 26 off to D&L to have this done. If I like it, then I would send in my Glock 17.

I want to stick with the Glock platform, and while I like the M&P ok, I don't like ambidextrous safeties and the safety sits a little high for me.
DocGKR, would you still recommend this modification?

Has anyone else tried this modification?

10 Ring Precision put one on a 26 for me about ten years ago and it was very mushy and vague. The safety relies on friction with the frame to stay engaged. There's no detents.

I ended up filling in the cut in the frame with plastic bumper epoxy and gave the pistol to a friend who is still using it.

As noted above, the D&L/Cominolli Glock Safety is quite positive in engagement and can be adjusted in this regard--it does NOT rely on friction with the frame. If you don't desire an ambi safety, it works well.

None of the images seem to work. I'd love to take a look out of curiosity. That said, I'm perfectly happy with my "Gadget" setup as it fulfills my safe re-holstering need.

I emailed them and was told no.

Also do not work with 26,42,43 if I understand correctly.

I’m reviving an older thread here, but DocGKR curious do you still run the manual safety on your Glocks? I’m thinking of getting it added to my G19.3 along with an SCD.

If you do, any sense on where to get non duty kydex holsters for AIWB that fit them? Would a gunsmith be able to modify them? Any recommendations if so? I believe your in the Bay Area as well like me.

I have a few of these safeties and 30 seconds with a brûlée torch works to add clearance for them in kydex.

Did you install them yourself or have it done?


Really wish they offered something like this for Gen 5 Glocks. A well done thumb safety by someone like LTT would be amazing.

What do you think the answer to that question is hahahaha.

I bought the cutting jig and it’s pretty straightforward to do.

I also like knowing how all the parts go together on something like this that’s aftermarket in case of failure down the road I can troubleshoot better if I know the components rather than be left with a broken black box.

I went down this road, and now my Glocks are without thumb safeties :(

The D&L is a great improvement to the the base Cominolli. It still put the lever too low for my grip, into the "meat" of my off-hand palm. I got the levers remade into a location I liked. And for a while, life was really great, and operating both the thumb safety and SCD was really nice.

It may have been an artifact of the installation, but the friction-bearding bits of the safety that face against the frame eventually wore grooves into my guns. This became manifest when I was shooting weak-hand in a match and the safety kept popping on. Some system to positively detent the safety into its on and off states would be a big advantage.

Looking at the OZ9 with its metal chassis, it looks (I think??) like it might be a better candidate for a useful safety. I might grab some M&P thumb safties and see what could happen.

Here's an alternative solution from BH Spring Solutions/RDIH: https://bhspringsolutions.com/index.php/product/unintended-firearms-discharge-stopped-tactical-safety-system-for-glock-by-rdih/

And the p-f discussion thread I initiated where I tested and reviewed it: https://pistol-forum.com/showthread.php?47886-Glock-17-With-RDIH-BH-Spring-Solutions-Tactical-Safety-System-and-Vega-Level-2-3-Duty

The BH SS/RDIH doesn't permanently alter or damage the receiver; the Glock OEM slide cover plate is removed and the BH SS/RDIH system inserted in its place; it's a plug-and-play proposition. The main cons are the lever ergonomics are such that it's mose easily engaged and/or disengaged with the support hand as opposed to the dominant hand thumb, and that field stripping is modified, and requires using an enclosed tool.

It works well with most holsters, but with a level 2/3 holster with a hood, you'll likely need to modify your Safariland; I use the Vega level 2/3 with the right hood, which works nicely (I included it in the thread review).

It's not perfect (but it would be closer if the levers were just a tad bit longer), but it is eminently usable, and without requiring any alterations to the frame.

Best, Jon
