Actually, I don't dislike Glocks, and think they are better than pistols that are both DA/SA. THOSE are a hazard. Folks just have to treat that Glock with wide respect, and holster them properly, and NEVER put the finger in the guard until ready to fire.
Glocks are fine pistols for a lot of people. That said you like what your are used to and what fits. For my hands glocks have horrible ergonomics. And the ugliness of a glock is noteworthy :) For me there is no finer fit than a SIG
This link says G21. If so, I'd be surprised. I would have guessed 9mm.
