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.

    PX4 trigger job in a bag

    Posted by Roger on May 30th 2024

    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.

    px4 trigger job in a bag

    Posted by scott on May 29th 2024

    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.

    PX4 TRIGGER JOB in a BAG

    Posted by Robert Santana on Feb 29th 2024

    I have two PX4'S. I installed the trigger jobs about 3 weeks apart. This gave me a great opportunity to truly compare the difference in trigger feel and reset. WOW!!! It is such a huge difference. Well worth the money. I don't pull up and to the right anymore with my follow-up shots. If you're on the fence, and can afford it, I say, "Pull the trigger and buy it!"

    Very happy with the results. DA pull is much smoother, great for a carry gun. Trigger is a little lighter but it's the lack of grit and chop that is the big payoff. Read the comments below the install video for some pointers that will eliminate 99% of the install frustration.

    Vastly improved

    Posted by mark gander on Oct 15th 2022

    I recently installed the kit with the optimized trigger bar,and 11# trigger spring. To say the least the reset is crisp and the DA/SA is much lighter cant tell the number. I carry mine off duty and love the PX-4 unfortunately has never gained popularity guess folks like them striker fired pistols. Iam like Ernest cant beat a DA/SA pistol cant get safer.. In closing the factory trigger is good but trigger job in bag is better. Well worth the $214. I to have put many rounds down range with it and this is a vast improvement. The LTT folks are great and will answer all your questions. Stay safe and keep practicing. Regards M Gander Paris, TN
