❓ Frequently Asked Questions

Q: What is a non-threaded barrel?
A: A non-threaded barrel has a smooth muzzle with no external threading. It fits flush with the slide and is ideal for concealed carry setups where suppressors or compensators aren’t needed.

Q: Will this fit my standard P365 or XMACRO?
A: No. These barrels are specifically designed for the SIG P365 XL with a 3.7” slide. For other models, visit our standard P365 or XMACRO barrel pages.

Q: Do I need a gunsmith to install this barrel?
A: Not at all. These are drop-in barrels—just remove your old barrel and slide the new one in. No modifications or fitting are required.

Q: Are these barrels compatible with lead bullets?
A: Yes. These barrels use conventional rifling, so they’re safe to use with lead, plated, or jacketed 9mm ammo.
