I think you will find out what "works" and what doesn't as far as gear..
I had a "soft" holster, which was very comfortable, but I couldn't reholster without taking my eyes off the target. So right after training, Kydex holsters...
Also, I had thigh pouches for my M1A, and I found them to be fairly useful, but if they weren't tight enough, the mag would fall out while running, so the elastic ones didn't do it; the velcro did though.
Little things that become big things in serious situations. Also, I was very happy to buy a DAO pistol, as I tried my friends 1911 and couldn't work the safety in a panic. Nor could I work the Sigs (I'm left handed) under stress... In fact, I found out I couldn't work any of the DA/SA's under stress.... (probably can with proper training) but not something I preferred. Having two types of pull feel is not that great if you aren't use to it.
Oleg carries sometimes a Glock, but I think his regular carry is a Kahr 9 in Polymer..
Skunk..
What would be cool is if you bought the magazine, and the checkout clerk goes "Cool, Runt's on the cover this month!"
