there is a guy who did a torture test on his competition glock, look and you can find it....shot thousands of rounds out of it, dropped it out of a plane, ran over it...it continued to function. Ive heard bad things about glocks but reliability has never been one.
that said, i think the perfect gun for you would be the browning hipower....super accurate, its 9mm, and if you ever did decide to carry it, its doable. Plus its made by mr john browning, who also designed the 1911....you can kind of see the bloodline in both of them.
