AFTERBURNER + RAMJET FOR SIG SAUER P365®

The Radian® AFTERBURNER™ + RAMJET™ combo provide unprecedented recoil reduction and match grade accuracy in a concealed carry package. The threadless barrel design allows for effortless install/removal for cleaning, while LEGAL FOR SALE IN ALL 50 STATES*.

The AFTERBURNER™ compensator is machined from hardened stainless steel and the RAMJETTM barrel from hardened 416R SS; both are enhanced with a Radianite Black coating. This combination achieves low friction, high hardness, and high corrosion resistance, making overall durability and erosion from muzzle blast a non-issue. Angled front faces on the AFTERBURNER™ aid in holstering.

The INTRA-LOK® mounting system uses the taper lock principle; a tapered locking screw interfaces with an angled V-groove on the underside of the barrel. This perfectly times the
compensator as it locks down onto the upper barrel profile on the muzzle end of the barrel.

INTRA-LOK® allows the user to simply slide the compensator over the barrel, insert and tighten the locking screw, making for a simple and repeatable installation process. This system allows the user to easily remove the barrel from the slide for cleaning.

The AFTERBURNER + RAMJET FOR SIG SAUER P365 has received mixed reviews. Users appreciate reduced recoil and effective performance, yet some experience feeding issues and question its price. Installation is generally straightforward, though a few found it not to be a perfect fit. Overall, the product is liked, but concerns about reliability linger for some users.

Just Sexy as can be
Besides the fact that it takes the bite out of the gun, but it's by far the best p365 you can have now!It's more like a 7 out of 5 stars.

Game changer!
Is it over priced?Absolutely.This is radian we’re talking about.One of if not the best firearms companies out there.Do I have any regrets?No.It changed the P365x into a flush fit Xmacro build that shoots as flat as the 1911 I have in 9mm.The only hiccups I experienced is one of the mags would not lock back on last round.Not entirely sure it’s ramjet/afterburner related or a combo of it and the single mag.Just at or over 200 rounds so far.You need this in your life.

Ram Jet + Afterburner
Install is easy.If you cave a CA compliant P365, you will have to remove the LCI which is easy to do.Significantly reduces recoil.When speaking of shooting self defense ammo, I found that It shoots Federal Punch 124g. works best with this setup.Had malfunctions with other brands.

Is this compatible with the P365X version? Radians website lists the P365 and P365X separately.

According to Radian Weapons: This combination kit is for: SIG SAUER® P365® & P365X™ (3.1” SLIDE). They list it separately but use the same kit.

I bought a Ram Jet compensator system-Barel and compensater. I read that in order to tighten the compensater-I need a digital screwdriver & tighten to 15 pounds. How important is this. Can I just tighten it with the included screw tip with a wrench? Thank you. I see those screwdrivers are betweeen 50 to 200.00. I would like to avoid the expense. I do not want this put on wrong either, Thank you- Shawn.

Slide AFTERBURNER™ micro-compensator over the RAMJET™ barrel, tighten tapered screw to 15 in.-lb. Reinstall the assembled slide onto frame. Test function to complete installation. This is what the mfg. says you need to do I would follow there instructions so you do not void there warranty.
