Trigger reset

[JohnKSa]

The "pre-travel" is doing the rest of the work pulling the striker back to the fully-cocked position. So regardless of what you do, if you don't have pre-travel you're going to end up with a Glock that is essentially fully cocked anytime a round is chambered.

Because of the way the other passive safeties work, you need some significant trigger movement in order to make things operate properly. I'm not saying it can't be done, but short of doing a significant redesign of the internal operation of the pistol I don't see a good way to get rid of pre-travel without losing function of the passive safeties.

If you have a Glock, take it apart and look how the safety ramp and the trigger bar interact to get a feel for how much trigger travel you need to make that particular safety work properly.

: I've been using it for over 60 years myself.

I fired a friends 75B SA that had a trigger job and set up for USPSA Limited minor.
My son has a CZ Shadow (no firing pin interrupt)with a trigger job for Production class, and I have a 75B with trigger work to compete with my son in Production.

That 75B SA really did have a sweet trigger. I added a "SKOSH" to keep my comment accurate. There has to be some pretravel to disengage the firing pin interrupt. The FPI can be removed easily leaving less pretravel. The gun has a safety.

Sounds a lot like my 1911's. You still have the trigger safety.

I agree Jmorris. I remember the number of years that I ran around in IPSC with a 2# trigger, no creep, and no safety (Colt 1911) cocked and ready to fire.

Johnksa, the trigger safety can be safely notched. However, I believe with my mental picture of the trigger bar being lengthened in the rear and the position change of the firing pin safety tab would produce negligible pre travel (not counting the movement of the trigger safety). The first nano movement would have the rear of the trigger bar contact the angled tab on the trigger bar dropping the sear and releasing the striker/firing pin. To maintain the firing pin safety, it would be necessary to measure what travel would be needed to maintain the use of the firing pin safety.
The "drop slot" could be manipulted to be active. Gotta remember, this pistol was originally intended for the military. I can really appreciate having all that lawyered travel and heavy trigger. 'Course, they developed the NY trigger.
IDPA allows internal changes/improvements but you must not cancel any factory safeties.
Guys, think my picture through and see if there are any glitches.

Do ya think it would worK and why or why not?

I was going to suggest teh sti gp6 as well for a short reset. in fact, I'm probably going to end up selling my g17 and getting one. I"ve just never been able to get a glock trigger the way I like it. elite match is also a contender, I just can't find one without the rail

1SOW, firing pin interrupt? The notched cylinder? If so, I believe the contact surface of the cylinder and the tab could be minimized to be in concert with the trigger bar travel. Again, the changes would be radical and probably would not apply to self defense. Hmmmm, a little more thought about..................

No you don't. If trigger pre-travel is significantly reduced then the trigger is already back past the point that the trigger safety can engage the frame. It will be completely ineffective.

I'm not guessing here. If you significantly reduce the pre-travel in a Glock pistol you will neutralize ALL of the passive safeties in the gun.

It's NOT like a 1911 unless you pin the grip safety of the 1911 and carry it off safe and cocked.

I believe with my mental picture of the trigger bar being lengthened in the rear and the position change of the firing pin safety tab would produce negligible pre travel (not counting the movement of the trigger safety). The first nano movement would have the rear of the trigger bar contact the angled tab on the trigger bar dropping the sear and releasing the striker/firing pin. To maintain the firing pin safety, it would be necessary to measure what travel would be needed to maintain the use of the firing pin safety.
The "drop slot" could be manipulted to be active.

I believe that if you completely rework the trigger bar and possibly modify other parts of the gun you can cut down significantly on pre-travel while keeping the trigger safety and the firing pin safety active. I don't believe you will be able to maintain the operation of the drop safety/safety ramp because it's going to require a decent amount of trigger bar travel to work. So you could probably keep 2 of the 3 internal safeties operational and still have very little pre-travel.

Just to be clear, that is NOTHING like simply removing the pre-travel in an otherwise stock Glock pistol.

It can and has been minimized (see CZForum re trigger pre-travel/reset point) but not significantly. The FPI has to go and the hammer hooks have to modified or replaced by the available "comp" hammer to significantly reduce the pre-travel. The comp hammer alone makes a huge difference--my son's gun has it.

On the other hand the pretravel can be made 'dead smooth' leading to a crisp break by polishing the fire control parts surfaces and replacing various springs.

 

[Red Cent]

6# trigger spring. 4# firing pin srpring. Reduced power firing pin safety spring.
Ghost Rocket connector 3.5
Mirror polished trigger bar on the frame side, connector where trigger bar rides, polished sear/striker contact, polished/smoothed firing pin saety tab, polished firing pin safety, and......

What comp hammer?

I talked to this guy and he assured me he was talking to the rest of you. Not me.

"Get Used To It

For shooters used to any other gun, the Glock trigger takes some getting used to. A great many of the most sophisticated Glock shooters are former and current 1911 shooters. Among them, it’s a universal first impulse as they start shooting Glocks to want to change the complex Glock trigger to make it feel like a simple 1911 trigger. It sometimes takes them years to realize that this is not only impossible, but a mistake."

I am looking at an ad for a complete drop in trigger housing/bar etc...that saaayyyyyyss........

"It eliminates all pre-travel and allows for adjustable overtravel, with the ability to completely eliminate it. Additionally, this kit brings the trigger back to a short reset point which gives the shooter faster and more accurate shots regardless of skill level."

Does not mention anthing about eliminating safeties. Seems like divine guidance is at work here. Or somebody who preys on "A" type personalities.

PS: Ignore my previous post.

 

[JohnKSa]

The safety ramp and the firing pin safety both require some significant movement of the trigger bar in order to deactivate them. Totally eliminating pre-travel while keeping those safeties working would be difficult.

The kit sounds interesting. I'd sure like to have one to fiddle with for awhile to figure out what they're doing and how accurate their claims are.
