I've shot my stock Glock trigger at half sized IPSC targets at 100 yds. Never proved to be a problem. In thousands of rounds, multiple years, and 15 courses now I've never had a moment where I felt the Glock trigger was the hindrance and not myself (now sights have been an ongoing battle that I never can make up my mind about).
What I said above wasn't to say that a decent trigger isn't important. I have no desire to shoot a terrible trigger. I guess IMO, and it is just an opinion, a lot of triggers out there aren't as terrible as some others think. I've owned literally every current production striker fired pistol. This isn't some blind loyalty to a brand. VP9, PPQ, P320, APX, M&P with full APEX kit, FNS, XDm with Powder River Precision kit, Ruger SR9, and most DA/SA pistols as well (with and without modified parts). I'll likely try the P10c at some point too, when a local store actually has it in stock so I can handle it first (if I had a complaint about CZ it would be the supply). I have noticed a difference among some with slow fire groups, but once I start moving at speed and doing more defensive minded drills I find other factors like the ergonomics for my hand, the bore axis, etc. have more of a play in what I feel about the pistol than just the trigger (layout of the controls becomes very important too as I have stubby fingers).
There are so many options out there these days that no one should be stuck with a pistol he/she doesn't like. I just get tired of reading "this trigger sucks" etc as I often see people taking opinions and treating them as undeniable facts. It's a pet peeve. But at the end of the day you should trust and enjoy what you have.
To me, the Glock trigger isn't the standard by which other triggers should be measured.
