I got your back Jay @jrtmasp - I put the Gen 5 version in the 19x around Christmas time, and just shot it a couple weeks ago - been hectic here. It's FUCKING UNREAL.
@JBMatt was with me, and shot it a few times, and decided he needed one in his life, so he got the Gen 3/4 trig for his gun. He hasn't shot it yet, only dry-fired it and worked it in.
It is hands-down the most badass trigger you can get for a Glock, I don't care what anyone says. I was doing 5-second drills with it the first time I shot it, and I made it harder on myself on purpose. Instead of 5 or 7 yards, I set steel at 10 yards. Delayed beep, don't ask me if I'm ready, don't tell me to stand by, when I tell you, just quietly hit the button, and I won't know when the beep is going off -I need it to be unknown...
Hands at sides, pistol holstered in a retention holster, wait for beep. The goal is 6 rounds on target, under 5 seconds, from the draw. Best I pulled that day a few weeks ago - first time working this trigger... 6 rounds on target, hands down at sides, pistol holstered. 3.14 seconds.
Don't think about it - just buy it. It's everything that they say it is, and even more than they say it is. You cannot go wrong, no way, no how. If you buy it and don't like it, I'll buy it from you (my money-back guarantee), then put it in my Gen 3 P80 G17 gun.
