You did very well, I have have the glock 32 and I really like it. I'm not a glock lover either, but the 357 SIG round is fantastic. I like my friends glock 20 in 10mm, but it's a bit large for even my large hands to be really comfortable to grip, so I went down a frame size and ended up with the 32. I'm not disappointed at all with the round or the pistol.
The 357 Sig uses 9mm/.355 diameter bullets, but when using hollow points for defense, be sure to use ones made for the 357 Sig as they are constructed in a more robust manner to handle the higher velocities of the round versus the 9mm Luger. You probably already knew that, just making sure.
