Radian Afterburner & Ramjet Combo for Sig P365 9mm

Description

The Radian Afterburner and Ramjet combo brings serious performance to micro-compact carry. This is a matched pair designed specifically for the Sig P365 and P365X with a 3.1 inch slide. The Ramjet barrel is machined from hardened 416R stainless steel with porting designed to work in concert with the Afterburner compensator, while both components receive a Radianite coating for enhanced durability and corrosion resistance.

Recoil Reduction That Works

The combo achieves up to 44% recoil reduction with standard 115 grain ammunition, which translates to noticeably faster follow-up shots and better sight picture maintenance during rapid fire. The Afterburner itself is compact, just 0.47 inches in length, delivering performance comparable to much larger compensators. Many users report significantly reduced muzzle rise, which makes a real difference when you're trying to stay on target during strings of fire.

INTRA-LOK Makes Installation Simple

This is where Radian's engineering really shines. The INTRA-LOK mounting system is threadless, meaning the Afterburner uses a tapered locking screw that interfaces with a V-groove machined into the barrel's underside. You slide the compensator over the barrel, insert and tighten the locking screw, and you're done. The taper-lock design automatically times the compensator, and you can remove the barrel for cleaning without any hassle. No threads means carbon buildup won't seize your setup, even after thousands of rounds.

Built to Last

Both the barrel and compensator are machined from quality stainless steel and finished with Radianite, which improves surface hardness and resists corrosion from muzzle blast erosion. When installed on a P365 or P365X, the combo extends your slide profile to match the P365XL length, giving you P365XL holster compatibility while keeping the concealable package you started with.
