I broke the edge on the slide ports with a round file and smoothed it out with 320 grit sandpaper. This black Caliber X-Change kit for P320 full size pistols allows users to switch centerfire to 9mm, and features a Nitron finish stainless steel slide/barrel assembly complete with green SIGLITE Night Sights, a full size polymer grip module and a 17 round magazine. Utilizing our magazine extension technology the Tyrant Designs Glock 19 & 23 magazine extension is the fastest and easiest installing mag extension ever! We have adapted our designs to integrate with and complement the design of your pistol so no longer does a compensator have to look like an afterthought slapped on the end of your pistol, Rather it Delivers unmatched performance and looks. Most competition clubs have a function fire bay. As expected with the 500 rounds down range and a pile of dry fire it's smoothed out.
