have small hands and sometimes my trigger finger will hit the trigger safety on the side and cause the trigger to stick briefly
I pull any new Glocks apart, and trim those two wee bars off the side of the center trigger safety, use a box cutter. Cures the push to one side and stick problem, that could get you killed.
While I have your attention, my Buddy a Glock match putter on Guy here in Orlando, tells me Dave Svigney(sic) mods his triggers to get a clean 4 lb release? All mine are standard 2k from the factory, very clean, but a bit heavy.
What's that all about?
