Good not perfect - SIG SAUER P320 9 mm 5.5in Pistol Barrels - Threaded

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.
