Trigger job in a bag px4 w/ trigger bar
Easily installed reduces trigger pull and travel tremendously
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.
In August 2025, LTT switched over to a newly designed optimized performance hammer to optimize total trigger job performance in every way with improved sear notch geometry, reduced pre-travel distance, faster lock time, and better firing pin indent with lighter hammer springs. We believe this kit set-up gives you the best Trigger Job Performance and stand behind this hammer design, which has been over a year in development and manufacturing.
The PX4 Trigger Job in a bag works in the PX4 Full-Size and Compact 9mm models and .40 S&W.
The PX4 TJIB had a price increase in November 2025 due to the price of steel and imports.

Can Do Upgrade
I wanted to setup my stainless steel PX4 Compact like a Langdon Compact Carry and this was the first piece of the puzzle. Many thanks to E.L. for the making his install video. I was able to easily do it myself and the trigger is definitely better than my other PX4s with only the D-Spring upgrade. Smooth DA with no grit or stacking, and a light crisp SA.
