The perfect way to upgrade or build a custom Carry-Sized P320.
Sig Sauer® has claimed their territory in the realm of the modular pistol with the P320: With it, you can swap calibers, frames, slides, and accessories in just seconds.
We wanted to take it even further by offering this custom full-sized build: The Sig® P320 Compatible Full-Sized Pistol Kit gives you with the parts you need to upgrade your existing Sig P320 fire control unit (or 80%-built MUP-1 chassis) with a 9mm-chambered barrel and full-sized P320 grip module (frame) with a textured, ergonomic grip and 17-round capacity.
In addition to the included frame/grip module, slide, and barrel, you're also getting a quality, US-built lower parts kit. This kit's precision-machined to OEM specifications with an upgraded trigger mechanism and is capable of chambering 9mm, .40 S&W, and .357 SIG as the P320 platform intended.
Included in your parts is the Armory Craft recoil spring tuning kit. With it you can choose between multiple included recoil springs, each with their own spring weight, and use the one that feels best to you when you shoot.
NOTE: This kit is not compatible with .45 ACP.
