Radian Afterburner + Ramjet P365 Compensator Barrel Combo

Radian Afterburner + Ramjet Combo System

The Radian Afterburner and Ramjet combination represents a thoughtful approach to enhancing the Sig Sauer P365 platform. This matched pair—compensator and barrel working in concert—delivers measurable recoil reduction while maintaining the accuracy standards expected of a quality defensive firearm.

Design and Construction

Materials and Durability

• Afterburner compensator machined from hardened stainless steel
• Ramjet barrel manufactured from hardened 416R stainless steel
• Both components enhanced with Radianite coating for low friction, high hardness, and superior corrosion resistance
• Engineered to withstand muzzle blast erosion without compromise

The INTRA-LOK Mounting System

Radian's proprietary INTRA-LOK system uses a taper-lock principle for repeatable, tool-free installation. A tapered locking screw interfaces with an angled V-groove on the barrel's underside, perfectly timing the compensator as it locks onto the upper barrel profile at the muzzle. Installation is straightforward: slide the compensator over the barrel, insert the locking screw, and tighten. The system allows equally simple removal for cleaning and maintenance.

Practical Advantages

• Concealed Carry Optimized: The combo increases overall slide length to P365XL dimensions, providing compatibility with all P365XL holsters
• Match-Grade Accuracy: Precision engineering delivers the accuracy expected of quality defensive ammunition
• Recoil Management: The compensator system works with the barrel to reduce felt recoil and muzzle rise
• Legal in All 50 States: Designed for unrestricted civilian ownership

Compatibility

Fits Sig Sauer P365 and P365X models with 3.1-inch slides. The system transforms these compact pistols into configurations compatible with P365XL accessories and holsters.

This is a purpose-built system for shooters who demand both performance and practicality from their defensive firearm.
