You're a moron. The only way that a barrel could be split like a banana peel is if it was overloaded with high powered rifle powder. My Glock takes +P Corbon, +Golden Sabre, and some other kind(Winchester or Federal, can't remember since GS are the best ever made) and I've never had trouble. The test rounds fired through Glocks can vary from 150% to 200% recommended loads. The can take double charged loads on a regular basis, and while it will increase wear on the bore and recoil spring, you won't get blown up. Also look up HK USP kb!'s and you'll find a lot of 'em. In addition NO polygonal(hex, oct, etc.) bores are not supposed to use lead bullets, it just makes for a tight fit(after lead build up) which causes too much gas to try finding another way out(it has even happened with a Desert Eagle: I saw the pics way back on the old Desert Eagle Shooters forum). Glock was pretty early on the hexagonal/octagonal bandwagon and morons that didn't understand what this meant stuck to their old ways. Thats all. Stupid people making stupid mistakes and screwing it up for the rest of us.
