Frequently Asked Questions

What makes the X01 chassis system unique for the Sig P320?

The X01 chassis is notable as the very first chassis system developed for the Sig P320, predating many other popular designs. It features a fully enclosed top cover, contributing to a distinct pistol caliber carbine aesthetic, and offers ambidextrous controls.

How can one improve suppressed shooting performance with the Sig P320 X01 chassis?

To optimize suppressed shooting, especially with subsonic ammunition, a specialized recoil system like the Harrington Arms recoil system is recommended. This system includes adjustable springs and end caps to fine-tune the firearm's cycling for reliable operation with a suppressor.

What are the key disassembly steps for the Sig P320 X01 chassis?

Disassembly involves extending the brace, pushing its release mechanism, and tipping it open. The slide is then removed from the chassis rails. To remove the fire control unit, a lever is flipped, allowing the slide to be sent forward off the chassis.

How does the X01 chassis compare to newer Sig P320 chassis systems like the Flux Raider?

While the X01 chassis boasts a unique, original design and impressive aesthetics, newer systems like the Flux Raider may offer advantages in reload speed. The X01's mag release location and upper shroud can add slight complexity to reloads compared to some other designs.
