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;

  • We are now offering the PX4 Trigger Job in a bag with the Beretta Competition Trigger Group again and not the factory trigger group.
  • 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). 

Delivery Time: 3-5 business days

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.

    My only complaint is it took me nearly a year to get my hands on one. No complaints whatsoever with the product itself. Very easy install ant a game changer re: performance. I’m very pleased with my purchase.

    Finally, the trigger I deserve in my Px4 Full Size. Worth every penny and the results were beyond expectations.

    10/10 recommend, easy install and great fit, with the trigger bad the reset is super short and crisp!

    11 pound spring chosen. Double action lighter, the SA reset is MUCH shorter and effective (but you have to train to get used to it). All in all, definitely worth it. BTW I made a mistake in gun assembly, and the Langon tech responded right away and helped (not them).

    Great Product. Easy Install

    Posted by TJIB PX4 on May 30th 2024

    Picked up a stock PX4 for cheap. Good trigger out of the box. This was easy to install (PX4s are intended to be easy to work on). DA feels about the same, but very smooth and a little lighter. SA is awesome. Trigger reset is tiny. Great buy. A must-have for your PX4.

    Awsome TRIGGER JOB IN A BAG - PX4!

    Posted by TimS on May 30th 2024

    This was simply an amazing upgrade! It improved an already great trigger to near perfect, removed most of the takeup and reduced the single/double action pulls by at least 25%. On top of that, following LTs video, it was by far the easiest trigger upgrade I have ever done. Thank you!

    Trigger job in a bag 9MM PX4

    Posted by Richard Morales on May 29th 2024

    It took me about 10 minutes to complete the replacement. Wheeler professional digital trigger pull gauage DA 4.3-5.0 / SA 1.3 - 2.0 The long double action is smooth, and feels like similar to the original trigger single action. The single action takeup and reset are incredible. I highly recommend this upgrade to anyone who owns a PX4.

    watched the video made it very easy to install. really smoothed out the double action and reduced the weight on the single action. but where it really shines is on the trigger reset.
