Radian Afterburner + Ramjet Sig P365XL Barrel & Compensator

Description

If you're running a Sig P365XL and want serious recoil management without sacrificing what makes the gun compact, the Radian Afterburner and Ramjet combo is designed exactly for that job. This is a matched set that pairs a ported match-grade barrel with a genuinely micro compensator—the Afterburner measures just 0.47 inches long, so it stays true to the P365's original mission as a carry gun.

Match-Grade Accuracy in Concealed Carry Size

The Ramjet barrel is machined from hardened 416R stainless steel and fluted for reduced weight. Radian markets this as match-grade, and the poring pattern on the barrel works with the Afterburner to manage recoil without adding clutter to your setup. Most users report meaningful improvements in follow-up shot speed and sight tracking, especially useful whether you're running drills at the range or training for carry.

The Threadless INTRA-LOK System Actually Works

This is where Radian solved a real problem. Instead of relying on a threaded barrel (which complicates things in certain situations), the combo uses a taper-lock principle. A tapered screw interfaces with a V-groove machined into the barrel's underside, locking the compensator down with repeatable, tool-assisted precision. Install and removal take minutes without needing gunsmithing. You can field-strip and clean without special knowledge or equipment.

Built for Real Use

Both the compensator and barrel get Radianite coating, a low-friction finish that protects against corrosion and erosion from muzzle blast. The angled front face on the Afterburner is designed to aid in holstering—a detail you notice when you're actually carrying. The combo increases your P365XL's overall slide length to match a P365-FUSE footprint, so you'll have broader holster compatibility.
