SIG SAUER P320 9 mm 5.5in Pistol Barrels - Threaded
Not a whole lot to say about this barrel other than it's OEM, seems to shoot as well as an OEM barrel ought to (I'm not shooting precision with it so can't weigh in on those fractions of MOA evaluations) and cycles and feeds like it should. I had it in a Flux Raider with a Sig Pro Cut 4.7 slide and ...

It’s probably perfect for any other P320. For an X5 Legion, it doesn’t fit. Total waste of time and money for me. Also, Thankfully I was at a range that was also a registered Sig Sauer dealer. The Range Officer told me there that sir had sent out a memo that no other P320 barrels would fit the X5 Le...

I own several Sig pistols streaching across many different platforms and have purchased threaded barrels for most of them. This one is no different then the rest. Despite Sig's current reputation there pistol barrels are fairly solid. They're generally everything you'd expect when purchasing. They drop in with no issues, accurate, easy to clean, and the qc on the threads are good (I never had an issue with the threads). However where Sig's pistol barrels fall short is in the finish. The barrel shows excessive premature wear after a low round count.
Pros:
Fit, finish (when new), accurate, easy to clean, good qc on threads
Cons:
Shows excessive premature where after low round count
Would recommend: Yes

I bought the Threaded Sig P320 Full Size Barrel. Both are awesome and as expected to be used to install a compensator or suppressor on the Sig P320 models. CAUTION to purchasers who wish to replace the Sig P320 X-Five Legion "bull barrel" with the full size threaded barrel as it doesn't fit properly. You must find a 3rd party manufacturer for a threaded "bull barrel" for the Legion.
Pros:
Works as advertised and reasonably priced
Cons:
Doesn't replace Bull Barrel in P320 Full Sized X5 Legion
Best Used for:
Compensators or suppressors
Would recommend: Yes

Reliable option for a full size 320. Used in a Raider build. Used an M17 first and later a 320 VTAC slide. Few hundred rounds and no problems with the barrel in either slide. Obviously the LCI had to be removed from the M17 slide. Would recommend when pairing with OEM slides.

Some expert answer on this or a compensator incorrectly stated the 5.5" barrel is needed for RXP Full-size. There was a half-inch or more barrel length than needed.
Pros:
None
Cons:
Too long for compensator with RXP Full-size
Would recommend: No
