After 20 years of service, the Beretta PX4 Full-Size has been updated to become even more shootable! The new heavy-profile cold hammer forged barrel in the PX4 G-Super Duty (G-SD) model mimics a gun Ernest built years ago and nicknamed “The Cheater Gun” for its shockingly flat recoil. The new G-SD is one of the softest-shooting 9mm handguns available.

The LTT Trigger Job includes the black DLC-coated Optimized Performance Trigger Bar that reduces the reset in single action to 1/10 of an inch, and the optional match hammer reduces pre-travel enough to rival world-class single action only pistols.  

Included:

  • LTT Trigger Job
    • ArmorLube DLC coated Optimized Performance Trigger Bar
    • Gunsmith-tuned trigger engagement surfaces
    • 11# Chrome Silicon hammer spring
  • G-model Carry-style decocker levers
  • Extended magazine release button
  • Two 17 round magazines and one 20 round magazine. 
  • Rubber Talon Grips (not installed) 
  • LTT logo engraved on slide

OPTIONS: 

  • RDO cut:
    • Similar adaptor plate as the LTT 92 RDO system with an integrated back-up rear sight that is matched to the height of the replaceable front sight for proper point of impact. Please Note: RDO Slides are re-cerakoted, and this process will cover the painted red dot on the decocker lever area. NP3 Package:
    • Cut and crowned barrel, LTT Trigger Job and NP3 on the trigger group internals, the magazines, hammer and barrel. *NP3 Guns will still receive a DLC coated Trigger Bar*
  • Gray Guns Steel Flat Trigger:
    • All-metal replacement trigger
  • Compensator, Pistol Light + Springer Precision PX4 Magazine Extension Kit - ADD ON HERE

    Px4 Full Size

    Posted by Michael Vascik on Mar 10th 2025

    The Px4 GSD is a solid performer. It is the first polymer framed handgun that the large back strap actually feels good in my 2XL hands. With the LTT treatment it just puts a huge smile on your face and causes you to expend lots of ammo. I am very impressed with the work Langdon Tactical does, the options they have, and their pricing. I am also impressed with their excellent customer service, which nowadays is rare. This was my first purchase from LTT, and it will be the first of many.

    Favorite gun yet!

    Posted by Keanu Sy on Apr 16th 2024

    I thoroughly enjoy this gun. I got my first one back in March and have been using it in USPSA CO since, and I liked it so much I got another recently! It's been dead reliable and extremely soft shooting.

    LTT PX4 Carry (Full size)

    Posted by Chris F. on Oct 30th 2023

    Received my full size LTT PX4 Carry last week and WOW, what an amazing pistol. It was everything and more than I have come to expect from the awesome crew at LTT. The trigger job is fantastic, the RDO cut and mounting system is perfect, the cut, crowned and cerakoted barrel is spot on, and the sniper gray cerakoted slide is gorgeous. I was hesitant to purchase a PX4 because I'm a 92 guy who prefers an all metal pistol. I knew that Ernest was a strong proponent of the PX4. and I decided to grab one after I saw him list it as among his Top 5 Favorite Firearms. I'm happy that I decided to purchase one. Its accurate, light, ergonomic, and the muzzle flip is lessened by its rotating barrel design. Its everything and more I expected it to be, and it has quickly become my favorite pistol for EDC. Thank you Ernest, Aimee and everyone at LTT for another exceptional pistol!!!

    Amazing Firearm

    Posted by Alex Glenn on Sep 13th 2021

    Great trigger, great recoil impulse and sight return, great optic mounting system. If the PX4 series was more popular, I think this thing would start showing up all over the USPSA and IDPA scene. Big fan of the money I spent.

    PX4 Full Size NP3

    Posted by RT1 on Nov 9th 2020

    I wanted to wait some time before reviewing this gun so I could spend time with it. I have shot a multitude of handguns and own a good amount, but this gun hits every category. The rotating barrel mechanism makes for an interesting and great low recoil shot, putting me on point for the next quickly. I’ve shot px4s out of the box, but what this company achieved was special. The smoothed out edges makes it desirable as a carry even in the full size (Glock 19 size). The np3 and trigger job accentuates the rotating barrel and makes it so much fun and accurate to shoot. The DA/SA trigger has a light pull and a short reset, and the polymer on the frame lightens the gun and aids in a well balanced firearm. Aesthetically, the tri tone finish looks great and I went ahead and added the spurless np3 hammer which I found fit the retro space look the gun already has. I, like many dismissed the gun when I first saw it, but damn was I wrong. Adding Langdons expert modifications only made me realize how wrong I was. I hope they keep making these so more people can see what they are missing out on. This is definitely in the top underrated handgun category and I think takes number 1 for defense and range use. Langdon took and idea and made it even better and I wouldn’t have wanted to discover this gem any other way, thanks.

    Outstanding

    Posted by Howard Marbury on Aug 12th 2020

    The customer service was amazing. I have wanted an LTT PX 4 ever since one of my clients came in with one. Soft shooting with a big orange front sight. So I ordered one with the red dot cut, boresight grip package, NP3 and the trigger job. No excuses with this one. Outstanding work by LTT. Learning the ways of the DA/SA and having a blast doing it.

    I am extremely happy with the time frame I received my pistol. It was 4-6 weeks and I got it in 5 weeks and am extremely happy with it. It everything and more you claimed it to be and what I hoped it would be. Looks are phenomenal, trigger is so light and smooth and crisp. Cant say enough about it
