Description
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.
NOTE: DOES NOT WORK WITH LOADED CHAMBER INDICATOR

I had high expectations
I underestimated what a difference it would make. The installation was quick and easy. This thing is not just another accessory that looks cool. This takes your handgun to a whole new level of control and handling. The follow up shots brought to mind shooting a BB gun. The barrel just wants to keep shooting in the same place. It was like shooting an entirely different gun.

Good Investment
Drop-in installation, about as easy as it gets. Really helps muzzle flip to help get back on target. Does lengthen the barrel, so you'll probably need a new holster.
