Trigger Job in a Bag - PX4

(20 reviews) Write a Review

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.  It will NOT work on the PX4 subcompact or .45 PX4 Full-Size and Compact. 

PX4 Trigger Job in a bag includes; Beretta Competition Trigger group for the PX4, 12# Wilson Chrome Silicon hammer spring and a Beretta Trigger Bar.

    PX4 Trigger Job in a Bag

    Posted by George Martin on May 9th 2019

    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.

    Px4 Full trigger job in a bag

    Easy to install with video. Only issue is when removing first pin it helps to depress upper retaining spring. Took 5 mins to install. I have 11 # spring; trigger much smoother, lighter pull and more consistent. Easy to “double-tap”. Would recommend to do this upgrade.

    PX4 Trigger Job in a Bag

    This was everything I had hoped it would be.
    Had previously installed a Beretta Competition Hammer group, but it did not accomplish what I had hoped for. The Langdon kit totally transformed the gun's trigger action.
    Easy to install (thanks to Langdon's video), and worth every penny.
    Especially grateful to the Customer Service Rep (Tammy?) who answered my concerns before placing the order.
    I am now a major fan of Langdon Tactical.

    PX4 Trigger in a Bag

    What a great product! This turned my already outstanding PX4 Compact into a super outstanding pistol. The DA Trigger is smooth and offers you the ability to make a constant pull on the trigger for that first shot by presenting the same resistance at the start of the pull all the way through the breaking of the shot. The SA allows for enough take up after the shot has broke that you can stage the trigger to the point of resistance and be ready for the sights to fall back on target.

    I also installed the Spurless Hammer which aligns perfectly with the slope of the rear portion of the slide giving the pistol a slick appearance and nothing to grab on to clothing while concealed.

    I highly recommend these parts for anyone wishing to make an improvement on one of the finest fighting pistols on the market. They will allow you to improve your DA/SA shooting skills and certainly turn a few heads of the striker fire fans.

    DA improvement; SA transformation

    Posted by Elijah on Nov 28th 2018

    This kit was easy to install, thanks to Mr. Langdon's thorough installation video. I bought the kit with the 12 pound spring, though I probably could have gone with the 11 lb with no problems. I noticed immediately that the DA pull was smoother and more consistent, but only slightly lighter in pull weight. The SA trigger pull is a complete transformation, and in my opinion the best thing about this kit. SA pull is light, with an incredibly crisp break. Incredibly fast shipping too; I ordered Sunday evening, LTT shipped the kit Monday morning, and my new TJIB was installed Wednesday. Very impressed with quality of product and customer service. This shop is now my go-to for anything Beretta.

    Significant Improvement

    Posted by Christian A. LaFalce on Nov 4th 2018

    DA is smoother and lighter, seems to stack less. SA reset is short and noticeable both audible and tactile. Sight picture acquisition on follow-up shots is easier. My groups were tighter and more accurate.

    Excellent purchase experience through Langdon Tactical.
