New 4th Generation Glock?

[ericire12]

I wouldn't want to do that. I can see you already know everything about everything. Signed, Mister Two Posts

We try to be cordial around here. So, BE NICE! 






P.S.

Jumbo -- Do yourself a favor and buy yourself a Glock..... ANY Glock. You wont be disappointed. The only real differences in the evolution of frame design is purely cosmetic. If you look hard enough you can find used Glocks that are as just as fine of performing guns as the new ones for under $350:

My only gripe, as I've said before, is the longer than single action trigger pull, and that is just a matter of personal preference, and a LOT more time on 1911's and revolvers than DA pistols.

Maybe I'm mistaken but, with a stiker fired pistol, are they really double action or since the striker is cocked against spring tension when the round is chambered, doesn't that make the trigger assembly a single action mechanism?  I quess my problems are that I just don't trust striker fired pistols for any reason regardless of the manufacturer.

Being an engineer and understanding the physical forces involved, it really bothers me that the striker can advance forward given the right conditions or wear on the other components of the trigger mechanism.  Maybe I need to a lilttle more homework to better understand the working parts of these pistols.  Like Tom, my primary experience is with my 1911, several revolvers and my old Beretta.

Timothy,

I view them as a true double action.  The difference is that you are not pushing a hammer back against a spring and then releasing it against a firing pin with a spring on it.  Instead you are pusing a spring loaded striker back and releasing it against weaker spring pressure.

My simple mind pictures it as both systems use a spring to both hold the firing pin away from the primer and to push the firing pin into the primer.  One is done by a spring loaded hammer swinging into the firing pin, and the other is a firing pin with opposing springs that is released to hit the primer.

Ok, having thought some on this, I have another question.

On a conventional hammer fired pistol, the firing pin itself is held, while in battery by the compents of the sear and spring assembly but the hammer MUST be dropped against the pin, forcing the pin AGAINST spring pressure to strike the chambered round.  The distal end of the pin cannot strike the primer unless force is applied from the hammer thereby compressing a spring.

Am I correct in assuming that in a striker fired pistol, the firing pin is held in battery AGAINST spring pressure and spring pressure is RELEASED and sends the pin to strike the chambered round when the trigger releases the sear?  This design lends itself to accidental discharge based on the physical forces required to hold the striker in place.  Yes, there are safeties designed into the system but, anything made by man is IMPERFECT and subject to physical forces beyond his control...

I still want to be the one and only reason that my pistol goes BOOM.  Physical force, applied when required.....not by failure of design or function....

Striker fire is a different classification then DAO.

With DAO the firing pin is forward and as the trigger is pulled it moves backwards to a certain point and then is released (Exactly like a DAO revolver). With a striker fire handgun the firing pin is already in the rearward position. A Glock is a striker fired pistol.

This design lends itself to accidental discharge based on the physical forces required to hold the striker in place

Glock and many other striker fire pistols have a firing pin safety in place until the trigger is pulled a certain distance and disengages the safety. It essentially blocks the firing pin from striking the primer if the sear were to fail.

http://www.glock.com/english/index_pistols.htm

FIRING PIN SAFETY
The GLOCK firing pin safety is a solid hardened steel pin which, in the secured state, blocks the firing pin channel, rendering the igniting of a chambered cartridge by the firing pin impossible. The firing pin safety is only pushed upward to release the firing pin for firing when the trigger is pulled and the safety is pushed up through the backward movement of the trigger bar. Releasing the trigger will automatically reactivate the firing pin safety.

The bottom line here is that the only way in hell that a Glock is going to go bang is if the trigger is fully depressed.

Thanks Eric...

Is there a recommended interval of replacement of these parts by Glock?  How often is cleaning of this part of the slide recommended and can the parts be re-installed improperly and adversly affect the safe action of the system?

[ericire12]

No clue

I'll have to do a little more homework I guess. 

Since I can't buy them new, only LEA remanufactured are allowed up here because MA considers them DA pistols and the law says they must have a 10lb trigger pull.  I know, M&P probably are lighter but S&W gets a pass...  Anyway, they have to be pre-1994 pistols that Glock reconditions.  The SR9 just got approved but still the "Turd" issue persists....

The only ones I would considered would be the compact models and doubtfull an LEA are going to be turning those in since they probably never used them.  I've yet to see anthing smaller than a G19...

 Point taken. I Will be nice. I will Be NICE!!!  I am a Glock Armorer. I have owned Glocks since the early 1980s and I believe in them. I retired from cop work in 1995 after 25 years and now work as a civilian for the State Dept. of Safety and still carry Glocks.  Glocks break. I have never gotten a service interval or schedule of replacement from tham and I know what tends toward breakage and keep those parts at hand. NOTHING is perfect. At least nothing mechanical...but Glocks are pretty far down that road. I admit to only 3, now, posts on this forum but have tens of thousands on forums and have really looked forward to this board.
If you are gonna jump my bones about Glocks on here tell me that you have been carrying them or fiddling with them for a while and I'll happily listen. Please don't tell me you'd like to own them if only you could afford them and then tell me what a POS they are.
