Trigger Job in a Bag - PX4

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;

  • The Beretta Competition Trigger group has been discontinued for the PX4 due to the environmental standards.   We are still offering the PX4 Trigger Job in a bag, but please note, it is not chrome plated, the trigger group is black. 
  • Chrome Silicon hammer spring available in 10# or 11# 
  • Black-DLC Optimized Performance Trigger Bar
  • Hammer: Factory, Spurless or Match (If you select spurless or match, you will receive the factory hammer as well in the bag). 

PLEASE NOTE: This kit MAY require some fitting for proper install and function - please make sure to watch the install instructions video, see below for the link. We recommend that this kit be installed by a competent gunsmith. No returns will be accepted on opened kits.

    Made ordering error. I have the sub-compact, so I can not use it. Hope I get to exchange it for a trigger on a different handgun. a

    Px4 trigger in a bag

    Posted by Ken on Jun 27th 2020

    Just got back from the range. Installed a PX4 trigger in the bag, 11 pound spring with the optimized trigger bar in my 9mm compact. Shot my full size with factory trigger first and had a 4 inch group. Switched to my compact with the new trigger and had a 2 inch group, 7 yards away. Had a range master with me and he also commented on how instantly you could see a difference on the target. I'm not a competition shooter, just hit the range about two or three times a month. It was easy to install. Wish I could attach a pic of my target to the review...

    A must have for PX4

    Posted by Zachary Howard on May 13th 2020

    This product is a must have if you own a PX4. This improves both the single and double action trigger pulls and drastically shortens the trigger reset.

    TJIB with OP trigger bar

    Posted by Mark on May 11th 2020

    Quick service. Great product. The hand polishing and stonework on the sear and hammer, make this a crisp trigger system. The OP trigger bar work# as advertised in reducing over travel and reset. Really transformed my Px4 over the stock trigger system.
