Looking to pick up a threaded barrel for my P320 Carry, now that it has suppressor sights and an installed RMR.

Looks like SIG makes (and actually has in stock?!?) a 9mm barrel threaded 1/2x28 which should work, but it shows as a 4.6" barrel. The stock barrel is a 3.9", but I'm assuming the threaded one is 4.6" because of the threaded portion?

And has anyone installed a threaded barrel on their P320 carry, and if so, what threaded barrel do you recommend? SIG? Other manufacturer?

Thanks in advance.

I bought a P320 compact/carry threaded barrel from Proven Outfitters for a great price. It has the metric left hand threads and no LCI hole.

P320 threaded barrels are quite long and stick out from the slide pretty far, so the 4.6" length on a compact/carry threaded barrel is correct.

By advised that there area slight differences between the older X-Carry slides and newer carry/compact slides so some barrels my not quite fit properly depending on this.

Good to know. Thanks. My P320 Carry is pretty new so hopefully it will fit correctly if I get the SIG barrel. I’m open to other brands but figure I’d stick with SIG if I can find one as *hopefully* all would fit together well.
