This was my first Killer Innovations barrel. The one I purchased was a gold, non-threaded, for my Glock 19 upgrade build. Dropped right in, and cycles like a dream. No alterations or gunsmithing required. Smooooooth!

I installed the Velocity barrels on my Glock19 and P365XL Spectre Comp. These barrels are beautifully designed and are noticeably more accurate than stock. Definitely worth the money.

I recently bought a Velocity Defense barrel (tin) for my Glock 19 Gen 4. I followed the break in procedures including using the red grease and the barrel fit and performed flawlessly. The performance compared to another name brand aftermarket threaded barrel was a lot better. I hope yall start making threaded barrels for Glock 43’s and 42’s. Customer service was also perfect.
