This is going to be the longest 10 days of my life. Damn CA laws ;)
Congrats on the Sig. I just bought myself a Glock 19 the other day. (Paid for and taken home in 15 minutes- gotta love KY). I did get a chance to try out the Sig P226 and the SA XD at the range last week and I loved them both. It was a toss-up between the Sig and the G19, but since this was my first gun I decided not to spend any more than I could afford. The best part: went to the range again yesterday with a friend who has a HK USP .40, and after an hour he had spent $20 more than I had.
I'd buy a .22 rimfire. If you have not shot much handgun before, cheap practice ammo would be a good idea. Lots of practice is a good plan. You can always get a bigger hole in the barrel.
Picked a winner..Congrats!
.40 or .45.
Start with at least a .38 or 9mm and work your way up
I now see you went with the 9mm. Good choice plus shooting will be cheaper.
