Radian Weapons Afterburner + Ramjet for Sig Sauer P365

I’d been hearing about Radian’s Afterburner + Ramjet system for a while — especially from the Glock crowd — so when I found out they released a version for the Sig Sauer P365, I had to see for myself whether all the hype carried over.

So we headed out to Route 66 Sport Shooting Park to put it to the test. After a couple of hours in a private bay and roughly 200 rounds downrange, we came back with some pretty clear impressions — and honestly, some impressive improvements over the stock setup.

Right away, the thing that stood out is how Radian approached this design. Unlike traditional compensators that rely on threaded barrels and often add extra length right where you don’t want it on a concealed-carry gun, the Afterburner + Ramjet uses a thread-less, pin-secured setup that keeps the overall profile close to stock. In other words, you get the benefits of a comp without sacrificing concealability or holster fit.

On the range, the difference was obvious. The pistol shot noticeably flatter, especially with hotter +P defensive ammo. Sight tracking was easier, muzzle rise felt more controlled, and follow-up shots came quicker without feeling rushed. Even with the mixed bag of ammo we brought — everything from cheap range fodder to our preferred carry loads — reliability never gave us a reason to think twice.

If you’re carrying a P365 and want real performance gains without turning your everyday gun into a competition-length setup, Radian’s system delivers. The machining is clean, the fitment is tight, and the improvements in both speed and shootability are something you can feel almost immediately. Yes, it’s a premium upgrade — but after spending time with it on the range, it’s easy to see where the value comes from.
