❓ Frequently Asked Questions

Q: What’s the difference between a flush crown and a threaded barrel?
A: A flush and crown barrel is cut to sit inside the slide with no external threading. It’s cleaner, more compact, and better for concealed carry. Threaded barrels extend past the slide and require a thread protector or attachment.

Q: Will this barrel fit my SIG P365 XL or XMACRO?
A: No. These barrels are made for the standard SIG P365 3.1” slide. They are not compatible with the XL or XMACRO frames.

Q: Is this a drop-in part?
A: Yes. All barrels listed here are true drop-in replacements and require no gunsmithing.

Q: What finishes are available?
A: Black Nitride, Stainless, and Gold TiN—each offering different benefits in terms of wear resistance, corrosion protection, and looks.

Q: Can I shoot lead bullets through this barrel?
A: Yes. These barrels feature conventional rifling, which allows the use of lead, plated, or jacketed bullets.
