I'm now a believer in Glock. Amazing, simply amazing.
Before I bought my Glock, a friend showed me some videos of a guy just being brutal with his trying to destroy it.
He packed it in sand & water, baby powder & water, etc. It jammed once or twice, he would sling the gunk out of it and it would go back to firing. He dropped it off his house, drug it behind his truck and even dropped it into a field from an airplane. It fired as it should. The H&K he was comparing it to failed early, during the "let's see what gunk we can pack it in" phase. The Glock never did.
