I got mine for a house gun no safety to fumble with just point and shoot and the 17 rd capacity. When your life is on the line simple is better I like mine only shot 51rounds in it so far had it since about augest I like it I. Got the 2 extra mags instead of the 50$ rebate
They seem to be pretty big sellers at the Orlando gun shows. Price level and the seemingly continuous $50 rebate may have something to do with it. Most of the gun shops at the show seem to have them and move them. Hey they are affordable and will go bang when you pull the trigger. As a house or truck gun, or range shooter they are okay. I don't have one, but a friend does, and I have shot it more then a few times. No feeding problems, no misfires. It is an okay gun.
But Of Course,
