I love these threads. It's always the same. People who would NEVER buy one come on to tell the questioner that they, too, should NEVER buy one, while nearly all of those who have one say they're reliable. Not purdy, not light-weight, but generally reliable.
Me personally, I have enough weight on my belt already, so I would not buy a Hi-Point, but I have nothing bad to say about them because from everything I've read and seen video demonstrations of from people who actually used them, you literally have to hammer a bolt in the muzzle and C-clamp the back of the slide to the face of that bolt to destroy one. The last time this subject came up (that I saw anyway), someone actually posted the 40 second clip of the catastrophic explosion of that C-clamp demonstration as evidence that Hi-Points are pure junk. After seeing it, I found the full-length video, and it turns out it was part of a series of torture tests that a couple of guys put the pistol through with the express intention of proving it was junk, and they couldn't make it fail except by making it into a mini-pipe-bomb. Almost every YouTube performance test/demonstration starts by the reviewer voicing his leanings towards the notion that they're junk, and by the end, they're saying how surprised they are at how reliable they proved to be.
