Can't really answer that specifically, but something about Glock has alway's struck me as just a poor design. Their reliable, not all that damn accurate, but I've never bought into the "trigger safety" as being anything else than poor forethought on the reality of "safety" :uhh:
I can use a 1911 just as good as any Glock, and I don't have a problem disengaging the safety before presentation to the target while indexed.
The 34 is a great comp gun, but I just like my SIG, or H&K for real carry.
It's just my personal adaptation to a specific pistol.
