Easy install, perfect fit - Timney Triggers SIG MPX Straight Trigger

Put this trigger in my Sig Copperhead, pulled out old trigger, dropped this one in, put in the pins and tightened two screws, that’s it, 3.5lbs. I would recommend putting these in all guns they will fit. I read a review from a guy saying the pins fall out, yes they will until you tighten the screws that are in the trigger box, they put tension on the pins and I had no issues
