I own two hi-point pistols(in addition to Rugers, Rock Islands, Springfields, CZs, Colts, and Berretas...I can't ever seem to buy just one of anything), one in 9mm, and one in .45acp. Both have been absolutely reliable, and plenty accurate. I've never had an issue with mine, so I can't speak on their customer service, but my understanding is that it's very good. Hands down it's the best bang for the buck I've ever got out of a gun. They are big and bulky, however, so not the best for concealed carry(got a 1911 for that). I've put a few thousand rounds through each of them, and they both still run like a champ. I never intended them to be any more than plinkers, but after my experience with them, I'd bet my life on either of them. Once again, without question, the absolute best bang for the money I've ever got out of a gun, and I've owned a lot of guns.
P.S. they are polymer frame, but the slide is all steel.
edit: @Vader - gotta love the 'crap pistols' and all the crap we get for having them. Folk can poke fun all they want, I don't care, when I pull the trigger, it goes bang and there's a hole in whatever I was aiming at, without fail. I really can't ask for more than that. Though I do have to admit, they are ugly as sin.
