I do agree, if you're only going to have 1, a 19 is a great choice.

I got the 26 partly because it's uber reliable but mostly because I already had a 34 with lots of magazines. I do CC the 34 from time to time, but mostly in cold weather when I'm going to be outside with a coat on. It also conceals well under a sports jersey. Heck you can conceal a Mossberg Shockwave and a MAC-10 under a sports jersey that's a size too big.
