Fantastic Upgrade
First off, installation was tricky, but easy. Take your time and wiggle the trigger around to get the pin in/out. Secondly, what a difference! Length of pull looks farther than stock, but it doesn't feel any different. The feel of the pull is also more positive than the oem trigger. The little bit of polymer at the end of my oem trigger would flex and give me a perceived bit of slop. The GG trigger breaks precisely and the 90° angle feels phenomenal. I will definitely get another one when I get another PX4!
