Radian Weapons R0876 Ramjet + Afterburner Combo Fits Sig P365 3.10" Black/Gray Stainless Steel$409.95
Availability: In Stock
The Radian Weapons R0877 Ramjet + Afterburner combo is a precision barrel and compensator system engineered for shooters who carry a Sig P365 and want to tame recoil while maintaining the concealability and reliability that made the P365 famous. This matched set pairs a match-grade ported barrel with a micro-compensator designed to work as a unit, delivering measurable recoil reduction and shot-to-shot consistency in a compact footprint. It's street-legal across all 50 states and built from hardened stainless steel with Radian's proprietary Radianite coating—a low-friction, high-hardness finish that resists corrosion and muzzle-blast erosion.
Installation is refreshingly simple: the threadless barrel design and Radian's INTRA-LOK mounting system let you slide the compensator onto the barrel, tighten a single tapered locking screw, and you're done. The tapered lock principle ensures repeatable timing every time. Equally important, you can remove the barrel from your slide for cleaning without tools or fuss—a genuine advantage for daily-carry guns that see regular use.
Mounted on a P365XL or P365-XMACRO, this combo lengthens your slide to P365-FUSE dimensions, which means your existing P365-FUSE holsters will fit. If you're running a compact Sig and want match-grade accuracy, reduced felt recoil, and the ability to service your gun without a gunsmith, this is the kind of upgrade that makes real sense in the real world.
