New York trigger for Glock
The New York trigger is currently only available from Glock, Inc., and Glock Factory Certified Armourers. Since we are not a Factory Authorized Parts Distributor for Glock, we are unable to supply this particular trigger and at this time we are not aware of an aftermarket replacement.
Does the titanium striker and full length guide rod promote better accuracy in the Glock pistol?
In practical terms, I doubt that you would see any significant change in accuracy in your Glock by adding these items but they certainly won't diminish accuracy either. The primary advantage to the titanium accessories for the Glock is the reduction of weight.
The Glock comes from the factory with a full-length guide rod but the recoil spring is captured on the rod. Many shooters comment they get a smoother shooting Glock by replacing the factory captured guide rod with an aftermarket non-captured system like the ones we carry from Wolff Springs, Inc. Another advantage to the non-captured system is that you can alter the recoil spring rate by matching the proper weight recoil spring with the type of loads you are shooting. In terms of improving accuracy, this may have the greatest effect.
Is it safe to alter a hand gun that you are going to carry for personal protection?
From my experience it is better to keep the firearm Factory. You can upfit the other guns in your collection for shows and competitions, but I would keep my personal firearm the way it comes,other than sights, just for the simple fact, that if you do have to use it and something malfunctions with the firearm, the falt lies with the manufacturer of your firearm and not you!
