Picked this up for my P365 because I wanted to experiment with a micro-compensator for EDC. The fit and finish are top-tier. I’ve put about 400 rounds of various 115gr and 124gr through it so far without a single failure to feed. It’s reliable, which is the only thing that matters for a carry gun.

Concentricity is the name of the game when you’re shooting suppressed, and SilencerCo nailed it. My Omega 9K aligns perfectly with no hint of baffle strikes. The threads are clean and the included O-ring keeps the thread protector from backing off during unsuppressed sessions. Definitely a pro-level upgrade

been running the SilencerCo threaded barrel in my P320 for about three months now. To be honest, I was mostly looking for the suppressor-ready threads, but the jump in accuracy was a nice surprise. The lock-up is noticeably tighter than the factory barrel, and my groups have shrunk at 15 yards.

a very high-quality alternative to some of the more ‘flashy’ brands out there

What impressed me most was the machining quality. No tool marks, the rifling is crisp, and the black nitride finish is holding up against holster wear better than the OEM barrel did. It dropped right into my XL slide with zero fitting required.

If you’re on the fence, just do it, it’s a solid piece of kit
