RADIAN AFTRBRNR RAMJET P365XL BRNZ

The Radian Afterburner + Ramjet combo for P365XL brings match-grade accuracy and recoil reduction to your carry gun in a package that slides into any P365XL holster you already own. This threadless barrel system pairs Radian's stainless steel Afterburner compensator with a hardened 416R stainless Ramjet barrel, both finished with Radianite coating for corrosion resistance and durability. If you shoot a Sig Sauer P365 or P365X, this kit transforms your slide length to full P365XL spec—a real advantage if you want better ergonomics and sight radius without changing your entire platform.

Installation is refreshingly simple thanks to the INTRA-LOK mounting system. The tapered locking screw engages an angled V-groove on the barrel underside, automatically timing the compensator as it seats on the muzzle. Slide, tighten, shoot—no special tools or guesswork. Just as important, the threadless design means you can remove the barrel from the slide for routine cleaning without disassembly headaches. The Radianite coating handles muzzle blast erosion so you spend less time maintaining and more time at the range.

One thing to know: this combo is legal for sale in all 50 states, and it's specifically engineered for P365 and P365X frames (3.1″ slide). If your P365 has a loaded chamber indicator, this system won't work—the Ramjet barrel lacks the LCI cut and won't seat with it in place. For P365/P365X owners without LCI, you're getting a concealed-carry solution that doesn't sacrifice accuracy or control.

Frequently Asked Questions

Will this fit my P365 or P365X?

Yes, this combo is designed for Sig Sauer P365 and P365X models with a 3.1″ slide. However, if your P365 includes a loaded chamber indicator (LCI), this system is not compatible—the Ramjet barrel doesn't have the cut required for the LCI and won't seat properly with it in place.

Can I use my existing P365XL holsters with this kit?

Yes. The Afterburner + Ramjet combo increases your P365 or P365X slide length to P365XL dimensions, so all standard P365XL holsters will fit.

How do I install or remove the barrel?

The threadless design is tool-free. Simply slide the Afterburner compensator over the barrel insert and tighten the INTRA-LOK locking screw. To remove the barrel for cleaning, reverse the process—loosen the screw and slide it off. The tapered locking system ensures the compensator times consistently every time you install it.

What's included in this kit?

This combo includes the Afterburner compensator (stainless steel, Radianite coated) and the Ramjet barrel (hardened 416R stainless, Radianite coated). Both are designed to work together as a matched system.
