Glocks are a smart choice. Even died in the wool 1911 guys like Sgt. Pate eventually see the light.

For defensive purposes, .40 or .45 are a good choice. Both are
relatively easy to obtain. 10mm can be pretty hard to locate. Something to consider for your emergency/survival planning.
Any SBG in SoCal or traveling to SoCal who wants to become a better Glockmeister is welcome to attend a Defensive Handgun class that I teach. Glocks are supplied to students for use in these classes. No matter your level of expertise, you WILL leave this class a better shooter.
The company I contract with charges a goodly amount for these classes, so
send me a PM first, and I'll make sure you get a special SBG discount for the class. More info here:
