Vortex Defender CCW enclosed. FYI: I found a major issue with the factory 15 round mags last week. I’ve already reached out to the rep I know and he said he’s bringing it to the factory engineers. I’ll try to make a video on it soon. The gun runs like a sewing machine, but those 15 rounders are unsat. Short term solution is to tape the base plate. I’m waiting for after market base plates for it.
