Ery time i turn around BLING BLING! This is the C9 hi-point. Not the yeet cannon. Blowback opperated means you don't need a booster with your suppressor. Threaded in 1/2X28. Included is a non threaded barrel if you want it shorter, an extra slide with ghost ring sight, five 10 round mags, one 8 round mag, Compensator that i cant figure out how to install, an the factory grips. Pay the axing price an ill throw in a 50 round box of hollowpoints.
