SIG P320 Full Size – Threaded Barrel – Match Series Flame Fluted – 9mm
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
This Faxon Match Series barrel is a flame fluted, drop-in style threaded 9mm barrel for SIG P320 Full Size pistols. It uses stress-relieved 416-R stainless steel, a salt bath nitride finish, 1/2x28 muzzle threads, and a 1:10 twist.
This is the kind of barrel that makes sense when you want a real threaded P320 Full Size setup from a known barrel maker without buying fluff. The important part is the warning: this one is not compatible with M17 or X-Series pistols, including the X5 and X5 Legion.
Fitment
- Fits factory SIG P320 Full Size slides
- 9mm
- Thread pitch: 1/2x28
- Drop-in profile
Does NOT fit
- Not compatible with SIG M17 pistols
- Not compatible with SIG X-Series pistols, including X5 and X5 Legion
What it does
This replaces the factory barrel with a threaded option for comps or suppressor-ready setups and gives you a match-grade style barrel profile with flame fluting. In real life, this is about adding muzzle-device capability and stepping up the barrel itself at the same time.
Why it’s worth it
This one earns its place because the spec sheet is strong and the fitment line is clear. Good barrel, good brand, clear exclusion list. That last part saves returns and headaches.

Install notes
Even on drop-in barrels, always verify lockup, slide function, and safe operation before live fire. If you add a comp or suppressor later, re-test the gun instead of assuming all is well.
Verify before you buy
Verify your pistol is a standard P320 Full Size slide setup and not an M17 or any X-Series variant. That one detail is the whole ballgame here.
