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.
PX4 Trigger Job in a bag includes

Great product. Huge improvement on the double action. Light and smooth as butter. Single action was greatly improved too. Crisp clean break. Will be ordering more of these for the other px4s. Only thing I wish is that the reset was shortened but no complaints great trigger group!!
Easy to install and really improved my pistol. The only problem I had was the 11 pound spring made the SA trigger a touch too light. Swapped in a 12 pound spring and it's ideal for my use.
Had a Centurion Tactical with the Wilson Combat trigger job which I was happy with until I bought a LTT with the trigger job. Immediately bought a trigger job in a bag for my Centurion Tactical in hopes of replicating the trigger in my LTT and now am in love with both of my Beretta's.
The PX 4 comes with a great trigger, but after installing the new trigger job in a bag with an 11# spring. WOW!!!! What a great smooth feel. The double action is crisp and purposeful. While the single action is quick and lite. I had to change my technic a little, but it made one heck of an improvement.
smooth, clean and crisp- better than expected
Trigger pull weight is NOT as stated once installed. Numerous emails have proven fruitless to resolve my dissatisfaction. I tried to resolve before writing this review. Customer service is absent.
What can I say other than WOW, what a difference. The trigger group is so smooth and positive in both double action and single action that it just kind of makes you smile when you squeeze the trigger and the hammer falls. The double action is no longer something rather unpleasant that many times you just want to get past so you can enjoy the single action. The double action improvement is off the chart, super smooth, much lighter trigger pressure need, super clean break, really makes the gun handle beautifully. Only problem now is that my FS92 is going to need the trigger job as well, as I am afraid that I will never shoot it again with the factory set up.
Great trigger feel. I had the Beretta comp trigger group in there already and this is an improvement over that. I was hoping for a bigger improvement in the reset distance but overall a great upgrade.
Love the setup. Easy install thanks to the video. Smooth double action and crisp single, just as advertised.
