SIG P365XL / X-Macro – Barrel & Comp Combo – 3.7 in 9mm – Radian RAMJET + AFTERBURNER
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Radian Weapons built this version of the RAMJET + AFTERBURNER for the 3.7-inch SIG P365 slide family. That means P365XL and X-Macro slide-length fitment, not the standard 3.1-inch P365. You get the same threadless comp-and-barrel setup with cleaner recoil control and easier maintenance.
Available options are organized below under Variants. Verified finish options in this batch are Black, Bronze, and Black/Gray.
Fitment
- Fits SIG Sauer P365XL
- Fits SIG Sauer P365 X-Macro with 3.7-inch slide
- Caliber: 9mm
Does NOT fit
- Does not fit standard P365 3.1-inch slide setups
What it does
This system reduces recoil and muzzle rise with a matched barrel and micro-compensator setup while avoiding the usual threaded-barrel baggage.
Why it’s worth it
The 3.7-inch SIG crowd gets the same Radian treatment here: AFTERBURNER + RAMJET together reduce recoil up to 44% when using 115g ammunition. At only .47" long, the AFTERBURNER offers unprecedented performance in a micro compensator and is more effective than the majority of full-size compensators on the market. The INTRA-LOK mounting system uses the taper lock principle: a tapered locking pin interfaces with an angled V-groove on the underside of the barrel. This perfectly times the compensator as it locks down onto the V-shaped profile on the muzzle end of the barrel. Angled front faces on the Afterburner aid in holstering.
