Description
Langdon Tactical has done several thousand trigger jobs on Beretta 92s and PX4s, and the Trigger Job in a Bag Elite is their way of putting that same work in your hands. Instead of mailing your pistol off and waiting, you get the important internal parts pre-polished and hand-stoned so they arrive ready for a competent gunsmith to install. The result is close to the same trigger you would get if the gun went back to their shop, and for a lot of folks that means less downtime and more range days.
What the PX4 Elite Kit Does to Your Trigger
The heart of this Elite package is LTT's Optimized Performance Trigger Bar, coated in black ArmorLube DLC (Diamond-Like Carbon) for a slick, durable, corrosion-resistant surface. That bar is the piece that tightens up the single-action reset to right around a tenth of an inch, which is where PX4 owners feel the biggest difference. Pair that with the hand-stoned sear engagement surfaces and the factory pull goes from serviceable to genuinely crisp, with a cleaner break in both double and single action.
Fitment and Install Notes for the Trigger Job in a Bag Elite
This kit is built for the Beretta PX4 Storm Full-Size and Compact in 9mm and .40 S&W. The PX4 Subcompact runs a smaller trigger group and is not compatible. It uses your pistol's existing fire control group and installs with basic hand tools, but keep in mind these are LTT's parts and may need a little fitting for proper function. Langdon puts out install videos on their YouTube channel walking through the PX4 process step by step, and they recommend the work be handled by a competent gunsmith.
Why PX4 Owners Reach for the Elite Kit
The PX4 already ships with a respectable DA/SA trigger, so this is about refinement rather than fixing a problem. The improvement people talk about most is the shorter reset and the smoother, more predictable feel, which helps with faster and more controlled follow-up shots. Whether the pistol lives at the range, runs in competition, or rides as a carry gun, this is one of the most proven aftermarket upgrades for the platform.

Frequently Asked Questions
Will the PX4 Trigger Job in a Bag Elite fit my pistol?
This kit is designed for the Beretta PX4 Storm Full-Size and Compact in 9mm and .40 S&W. The PX4 Subcompact uses a smaller trigger group and is not compatible. If you have a Full-Size or Compact, you are good to go.
Can I install this Trigger Job in a Bag Elite myself?
It uses your pistol's existing fire control group and installs with basic hand tools, and Langdon posts step-by-step install videos on their YouTube channel. That said, these parts may require some fitting for proper function, so Langdon recommends installation by a competent gunsmith. If you are new to taking a pistol apart, having a smith handle it is the safer route.
How much difference will the Elite kit make on my PX4 trigger?
The biggest change people notice is the shorter single-action reset, which comes in at about a tenth of an inch thanks to the Optimized Performance Trigger Bar. The hand-stoned parts also clean up the break and smooth out both the double and single-action pull. It is a refinement of an already decent trigger rather than a complete overhaul.
What makes the Elite version different from a standard trigger job?
The Elite package centers on LTT's Optimized Performance Trigger Bar finished in black ArmorLube DLC, which is one of the most durable and corrosion-resistant coatings they use. This is their premium PX4 trigger package, giving you close to the same work they would perform if you shipped the gun to their shop.
