Disclosure: The barrels were provided by Faxon for testing and evaluation. Faxon did not see the video prior to publication, and no compensation was received. This write-up is based on the unboxing, features walkthrough, and outdoor impressions from the video — including range time with factory and hand-loaded ammo.
Channel fans and family — if you run a Sig P320 and you want a threaded barrel for a suppressor or a muzzle brake without waiting on OEM, this one’s for you. In the video we dig into Faxon Match Series pistol barrels for the P320: options, finishes, how they fit, and what happened when we put rounds downrange.

Why aftermarket threaded barrels matter on the P320
At the time of filming, Sig’s site showed a big pile of P320 models for sale (excluding the serialized fire control unit), but only a handful shipped with threaded barrels built to run a suppressor — including the P320 XCarry Legion and a couple of Custom Works guns (P320 AXG Combat and P320 Spectre Comp Blackout). Companies like Faxon filled that gap with Match Series barrels for the platform.
On camera I ran them in my used Sig P320 VTAC. The gold TiN barrel dropped right in and fit the way I wanted.
Options: size, length, finish
- Sizes: Compact and full-size (full-size is what I had on hand).
- Profiles: standard Match barrel, or a longer threaded option.
- Finishes: black nitride, gold TiN PVD, and chameleon PVD. I had both the gold TiN and the chameleon in the video — gold is the one that ended up living in the VTAC.
Faxon starts with stress-relieved 416R stainless, CNC machines the barrels in-house (including the flame fluting), then salt-bath nitrides them. The gold and chameleon versions get their PVD finish on top of that. Made in the USA. Price range called out on camera: roughly $175–$235 depending on size, fluting, and finish — generally meaningful savings versus OEM threaded options from Sig.
Fluting, drop-in fit, and the crown
Flame fluting on a handgun is mostly about looks here — the fluting is light. On rifles, fluting can shave a little weight and add surface area for heat; on a pistol that benefit is a lot smaller. What mattered more for me: these are drop-in ready. Older aftermarket barrels often needed a gunsmith and “drop-ins” could be sloppy. This Faxon Match barrel locked up tighter than the stock OEM tube in my gun — which tracks for a match-oriented barrel versus a more rugged, reliability-first OEM.
They’re conventionally rifled, so you’re not limited the way some aggressively rifled tubes are — lead, FMJ, moly-coated, and plated bullets are all in play. Muzzles get an 11° crown to help protect the rifling (and on the rifle side that crown style is a known accuracy helper).
Why the threaded tube sticks out
First thing you notice installing the threaded barrel: it protrudes farther than OEM. There’s a reason. P320s are tilt-barrel guns, and the guide rod sticks out — the extra length keeps a suppressor (or brake) from kissing the guide rod on the way back. Thread pitch called out on camera: 1/2×28, so you can run your choice of suppressor or muzzle brake where legal.
Range notes: factory ammo vs tight chambers
These are match-grade chambers and barrels — tight with some projectiles. Factory round-nose ammo was a non-issue. A friend’s thicker, more concave “bio” style bullets struggled to chamber fully; we showed that on camera (failure to go into battery, marks on the bullet). If you reload match ammo, you may need to watch sizing the same way you would with other tight chambers (think CZ territory). Faxon also had Duty barrels listed on the site at filming — cheaper (around the $100 ballpark in the video), not available yet then — aimed at less-tight chambers. When those land, they’re on the list to test.
I’d had these barrels about a year by the time of the video and put real time on them. Happy for gun games and steel. Finishes: gold is my pick; chameleon is fine if that’s your style — most of the barrel sits under the slide anyway, so what you see is mostly the muzzle end.
Bottom line
If you already own a P320 (or you’re moving somewhere you can run a suppressor) and your gun didn’t come threaded, Faxon’s Match Series barrels are a solid way to add 1/2×28 without OEM pricing. Drop-in, tighter lockup than my stock tube, multiple finishes, and real range time behind the take. Factory ammo behaved; handloads with fat ogives need the usual match-chamber care.
Keep on squatting. I’ll see you in the next video.
Are you threading your P320 for a can, a brake, or both — and which finish would you run?
