After several thousand trigger jobs on Beretta 92s and PX4s, LTT has the process down to a formula. We now offer what we call "Trigger Job in a Bag". Purchase this kit to receive all of the important parts involved in a trigger job that are pre-polished and stoned to give you close to the same trigger job you would get if you sent it to us. The PX4 Trigger Job in a bag works in the PX4 Full-Size and Compact 9mm models and .40 S&W.
PX4 Trigger Job in a bag includes; Beretta Competition Trigger group for the PX4, 12# Wilson Chrome Silicon hammer spring and a Beretta Trigger Bar.
