I have shot SA, FN, H&K, SIG, S&W, CZ, Kel-Tec and Glock tupperware pistols, Owned a H&K or two along the way, still own a G17 and a G34 Glock, use the G17 as a HD pistol with a Suerfire X400 on it's rail. The G34 is my USPSA production class pistol, tried to replace it with an STI Trojan and shoot just Single Stack but the G34 is just that good, and I am faster on the reloads. Going to BGSL this morning to shoot their USPSA match with the G34, still shoot better with the STI (just barely), but my stage times are faster with the Glock.
