Glock trigger / safety

I know that the Glock trigger is only partially cocked but it seems most other brand autos are fully cocked giving them a much better trigger. Although I am pretty invested in Glocks with holsters and magazines, I often wonder about moving to other brands. The one thing that gives me pause to changing brands is that I carry appendix, I have more confidence in a partially cocked to fully cocked gun carrying appendix.
Have anyone else looked at this subject?

The partially cocked glock striker spring has enough potential energy to ignite the typical 9mm primer
It is one of those glock myths that the partially cocked striker spring is a safety feature.

That said, you can buy replacement triggers that fully cock the Glock striker spring

TImney Alpha Glock
or
Glock Performance Trigger (GPT)

I would not conceal carry with a Timney installed, I would with a GPT
The two designs have some commonality, but the GPT is more robust and built by Glock to be drop safe.

They feel very different as well, I like the dry fire feel of the TImney more, however, I seem to shoot about the same with either. Not sure the dry fire feel matters.

It is one of those glock myths that the partially cocked striker spring is a safety feature.
Some years ago there were two or three videos demonstrating that stock springs do not have enough energy in their testing.
Either way, I am comfortable with Glocks other safeties, not being full cocked was just a plus.

A couple of thoughts for your consideration; First, a Glock won't discharge without the trigger being depressed. So the easiest and least expensive solution to your concern is simply to inspect the holster off-body for any FOD (foreign object debris). Insert the pistol in a safe direction and then place the pistol on body in your preferred AIWB position. And of course make sure the holster itself doesn't have any gaps around the trigger guard that would easily allow any FOD into the holster while on-body. This needs to be done each and every time. This is my recommendation for any pistol of course, particularly striker-fired pistols that don't have a MS. It doesn't make it 100% because there will always be the unlikely/improbable chance that 'something' could find it's way into the holster while on-body. But it does mitigate a substantially large part of what could be a problem. And it's really not a big deal to inspect the holster, insert off-body and then place on body. Takes 10 seconds or less and goes a long way towards preventing a discharge.

Secondly, if you do decide to change brands, perhaps go to a brand that offers a MS. I'd still recommend the above but having a MS engaged eliminates they small % that something unawares gets into the holster while on-body. And with a bit of proper training there is zero downside to a pistol with a MS.

I'll toss out a third option and that's to carry with an empty chamber. Yes, I know that gives some the vapors. But it is an option that is viable IF the person has been properly trained in the methodology. This is the safest way to carry since you can't have a discharge without a round in the chamber to discharge. And I would point out that according to Glock literature it is the way Glock themselves recommends their pistols to be carried. I'm not recommending this unless the person has some training but simply pointing out that it is a viable option for consideration.

If your trusting that Glocks partially cocked striker system is safer than other systems, don't. There is enough energy stored in the Glocks safe action system, it will set off most primers in the event the striker slipped off the cruciform and the striker safety block failed. I have tested this multiple times over the years.

Of course all other safeties would have to fail for it to happen, but just know their partially cocked system, isn't a 100% prevention.

With that, as others have said, the GPT completely changes Glocks current fire control system to a fully cocked system, like most other striker fired pistols. IMO the GPT is at least as safe as the traditional Glock firing system, and possibly even safer.

Either way, the one thing I enjoyed about my Sig P320, VP9, and a few others was the much cleaner, less disruptive trigger action and break as compared to my Glocks. The GPT gives me the attributes I like about the other trigger systems, but with all the other aspects of the Glock that I have come to appreciate and trust in the 30 plus years of carrying them on and off duty.

I can work a factory Glock trigger system just fine, but far and away prefer the GPT, especially with the VEX shoe added to the mix.

Having a better trigger is a big plus and maybe I will check out Glocks new trigger option. My Glock triggers aren’t bad, but compared to my S&W or Ruger it is.
One thing that started my concern was when I looked at the strike engagement recently with an orange backplate on 😲. That and the stamped metal parts parts and how the ends are finished.

One thing I like about the standard Glock trigger is that I can use an LTT striker control device. I appendix carry and thankfully belong to a range where I can practice from the draw and do so almost weekly. So thousands of draws/reholsters a year with a loaded gun.
Two of the guns I use in the local indoor GSSF league do have the GPT in them but we start from a low ready. But my first 500 was with a stock trigger gen5 19mos so there is not much difference between the 2 for me and certainly not enough for me to carry one with a GPT which cannot accept a striker control device.

Excellent point. When I reholster, my thumb is always on the “gadget” backplate.
All of my Glocks have the trigger control device.

When I hear discussions of the Glock trigger, I am reminded of something that Johnny Glock frequently points out. In a defensive situation and many competition situations, you shoot from reset. Yes, the Glock trigger is spongy. It's not a 1911 trigger. But the issues of over-travel and the speed of reset are often overlooked. Is the GPT better at reset than a stock Glock trigger?

Not enough to consider changing brands. If I want a SA trigger I'd opt for the GPT. As for AIWB? Any time I re-holster, I remove the holster from my belt line. Re-holster, then return the now holstered gun to my belt line. So I'm not worried about a SA trigger while carrying AIWB.

The standard Glock can fire without the trigger being pulled but the GPT can’t or, at least, I can’t manipulate it to fire without the trigger being pulled. The Timney, though it gets a bad rap, is also very safe. There is a spring that forces the trigger forward in the Timney and it relies on the same safety system in the trigger housing that a stock Glock relies. JG makes an excellent plus powered trigger spring for the Timney system that ensures full reset. If you are running a Timney system, it is a must for safety. I’ve done the JG spring with all my Timney triggers. The short trigger pull on the Timney is why people think it is unsafe and, if the trigger adjustment screw is pressing too far back on the trigger where the trigger shoe safety can’t catch, it can be very unsafe. That’s why they recommend an armorer install.

If you love a short trigger pull and the feel of a SA striker pistol, get the GPT and Vex. It’s the best thing out for those who think the stock Glock trigger feels more like the initial pull length of a compound bow than a trigger. IMHO, next best is Timney and Vex, Timney and standard Timney shoe, and then Gen 5 FCU and Vex, followed by some other systems.

Different strokes for different folks. Some like the stock triggers and they have that right. If it is safer for them or they are used to the feel, keep on truckin’.

I would like to hear how a standard Glock can fire without the trigger being pulled.

You can manipulate it to fire by pressing down on the cruciform. Let me back that up a bit. With a standard Glock trigger shoe and housing, it will not trip. With some of the aftermarket triggers that move the trigger back to a preloaded position, it can be tripped. Not saying that the standard trigger is not safe as it is very safe but there is a point, again, with some of the aftermarket triggers that can have some issues if it is too close to the drop shelf.

This 2nd reply seems to be moving the goal post quite a bit from the first assertion. And just how are you pressing on the cruciform? Is the gun in some state of disassembly? Something modified or swapped out?

Really talking Vex or other aftermarket trigger shoes in stock trigger housing as well as modifying the pre-load on a stock trigger. If one pre-loads the stock trigger too much and get too close to the drop shelf, it can be unsafe and you can press down on the cruciform and it will fire while the GPT doesn't seem to have the same issue with the Vex. That's why I used the term manipulation in previous posts. Stock trigger in stock position is as safe as any trigger it's when you get into different trigger shoes on the stock platform where you can have issues.

Some have posted their gun was not drop safe with a Vex in the stock housing and I can see why. It really preloads the stock trigger setup to the point that it can be unsafe. JG says it is fine and it has been fine in all of mine but it's right at the edge with a stock trigger arm and housing.

Does anyone know if a standard factory OEM unmodified Glock trigger, can fire if the gun is dropped if the connector is damaged or bent improperly? Or does the firing pin block prevent that? I have an old Gen 2 Glock 22 that was having issues returning to battery. Upon some advice from this forum I disassembled and tweaked the connector by bending it outwards a bit and then discovered that when I reassembled the gun the trigger no longer made contact and there was no resistance when pulled and it did nothing to move the striker. So I disassembled it again and tweaked the connector back the opposite direction a bit. Now the trigger works again when dry firing but my confidence in the firearm is destroyed and I'm afraid of loading it while not at the firing line pointed in a safe direction. I am worried that something in the trigger system will slip while it is loaded and the gun will go off accidentally. Is this an irrational fear? I am tempted to just send it in to Glock and let them overhaul it although being in California I really hate having to pay the $50 for the background check and 10 day wait just to get my own gun back.
