I purchased the velocity threaded barrel for my P365X. This barrel so much more accurate over the SIG stock barrel. I followed Killer-Innovations procedures for break-in. Even during the break-in, I had zero issues, FTE or FTF. This is a must upgrade for your weapon!! I have told all my friends that this is the barrel to buy.

The velocity barrel is one bad MF. Accurate as can be. First shots were at 50 yards and I was regularly hitting steel with semi rapid fire. The threading is top of the line, I could argue the smoothest threading on any of my guns. The machine work and the gold barrel stand out very nicely on my 365. KI gets my repeat business for sure.

I recently purchased a p365xl so it hadn’t been shot since it was in the factory. I have a silencer being approved so I figured I’d pick up this threaded barrel and zero it. I followed the break in procedure described in the video in their FAQ. They warn that during the break in process (300 rounds), failures of all types are common. I had 0 failures. Not one. I was able to get the barrel zeroed at 25 yards quickly and used a few mags near the end of the process to practice some from concealed fire. It was great. This barrel is well worth the money. I can’t wait to attach my silencer to it in a couple months.

Drop in 365 non threaded. Extremely accurate and no issues. Will def purchase more for other weapons.
