Sometimes I think I shouldn't bother; I really shouldn't; and, maybe someday, I'll learn my lesson and remain silent; but, today, and before another great internet gun forum myth gets started, I'm going to point out that,
IT IS POSSIBLE TO, '
STACK' A GLOCK'S STRIKER-FIRED (SO CALLED, 'SAFE-ACTION') TRIGGER MECHANISM - IT IS POSSIBLE!
And I've worked on enough Glock triggers to know. The factory knows, too; and back around 2008-2009 the specs on Glock trigger bars were changed in order to make it more difficult for this to happen.
An undesirable consequence of the lengthened, '
sear tab' and (slightly) increased, '
tab angle' on newer Glock trigger bars is to make it more difficult to get a smoother, lighter trigger on any Glock pistol produced with these longer, and more acute trigger bars. Consequently, the triggers on my older Glock pistols are significantly smoother and have considerably less, 'let-off' than on newer Glocks.
Neither am I the only person to notice this change. At the time, this subject was discussed in depth on GT; and JR Shepard (not me) was the first commentator to point out the recent changes in Glock's redesigned trigger bars.
The point is that it used to be easier to, '
stack' the trigger a pre '08 Glock; AND, depending upon the degree of wear, it's probably still possible to do it, now. (Wouldn't want to bet my life on it not happening, OK!)
THE SAFEST WAY TO RE:HOLSTER ANY STRIKER-FIRED PISTOL IS TO REINTRODUCE THE MUZZLE OF THE PISTOL INTO THE HOLSTER WITH YOUR TRIGGER FINGER STILL (RIGIDLY) EXTENDED AND, IDEALLY, ACROSS THE OUTSIDE OF THE GUARD.
This way, the trigger will be partially protected during the beginning of reinsertion; and there'll be a momentary pause as your outstretched finger touches the top of the holster. Now, you'll be better able to feel if the muzzle is being grabbed, or getting hung up on something that might, ultimately, impinge against the trigger.
(You want to be fast coming out of the holster; but not when you're going back into it!
Here, the muzzle acts like a probe. If it hangs up for any reason - even only slightly - you're going to have to stop, glance down, and take a look.)
