I've got one in 9mm, it works fine, and I have put several hundred rounds through it, with absolutely no malfunctions. It seems to be farily accurate, and I like the post in ring front sight, which for me instinctively centers in the peep. I wish the AR-15 had this option for a front sight.
Now, the downside, I think it's uglier than a prison zip gun made from rusted water pipe, and the plastic stock is very soft and deforms easily. The slap from the bolt transfers through the stock (which is the recoil buffer) right to my cheek like someone slapped me with each shot fired. Call me shallow, but I really prefer to shoot something which is easier on the eyes, like a nice classic wood and steel lever action.
Consequently, I really don't shoot the Hi Point that much, and wish I would have appled the $149 that I paid for it into a different gun.
I think it's the soft plastic stock, which feels like it would soften into spaghetti in the sunlight which really turns me off about the gun. The action of the rifle is really kind of innovative. Now, if someone just made good furnature for the Hi-Point, then you'd have something.
