I'm in the market for a new trigger system for my 19. My main goal is to shorten the amount of pre travel and have a shorter reset than stock. The Edge trigger system would fix both of those problems for me.
The Edge kit comes with Wolff reduced power firing pin springs at 4 and 4.5lb. And s Wolff reduced power firing pin safety spring. The site claims that with the 4lb firing spring the trigger pull weight will be around the 3lb mark, increase the spring weight and the trigger pull weight will also then increase.
My current set up in the 19 is a smooth faced trigger/trigger bar and (-) connector. With my scale the trigger pull weight averages 4.5lbs.
In theory, if I used the OEM firing pin spring and firing pin safety spring with the rest of the Edge trigger system in place of the wolf reduced springs the resulting trigger pull should still be around the 4.5lb mark?
