Description

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.

    PX4 Storm GSD

    Posted by Luke Allen on Sep 28th 2026

    So far I have put around 200 rounds through this gun and it might just be the best pistol I have shot so far. Extremely easy to control and make follow up shots. So far very reliable though I have only begun my experience with it. Definitely would recommend this gun

    LTT PX4

    Posted by Tyler DeWitt on May 6th 2026

    Got the full size LTT PX4 build from local shop RifleGear, flat trigger/RDO and all the goodies. It’s an awesome pistol and I’m kicking myself for not trying one sooner. Just a week ago I’d never owned or tried a Beretta, and now I have a 80X, LTT PX4 and LTT 92G Elite II ordered and on the way. I think I’m addicted now, thanks LTT!

    First 300 rounds through the gun today, not a single malfunction. Sure is a smooth shooter, and haven't even put the optic or comp on it yet.

    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.
