Well, just got home from a 24 hour shift to find a package I got from ROCKyourGLOCK.com ( only took 2 days to get here from time I submitted order online) and instead of sleep stayed up to install it. Only took 2 minutes and after adjusting it just right ( watch over adjusting it cause then u would have to take ur firing pin out) and feels amazing! Doesn't make the trigger any lighter or heavier but shortens the reset. I love it! Headed to the range as we speak.
