It's an inexpensive utilitarian carbine that utilizes the same magazines that are used for their pistols. Hi-Points are kind of like riding a moped, they work, but you don't want to be seen with one. Would I trust my life with one? Nope. Would I use one as a cheap fun plinker? Yep.
Yep, head shot of course. I don't own a Hi-Point, but one of my friends has one chambered in 40 S&W. He has put a good bit of ammo through it and I don't think I ever seen it jam. They also have a lifetime warranty. If I would run across one on a deal I would probably pick it up.
