I am a retired California LEO, so I have CCW privileges. For Every Day Carry, I carry a S&W M&P Shield in 9mm. With the Mag-guts +2 conversion in my mags, I have 10+1 of 9mm, less than 1/4" longer than the factory 8 rounder. It is loaded with Speer Gold Dot 124 +P Gold Dot (NYPD load) for about 360 ft lbs ME, even from the short barrel.
I retired my CZ 83 and Bersa 380 when I switched to the Shield. It is so compact and light, I forget I am waring it in a leather IWB holster. I also occasionally carry (when I go to LA or SF areas) my trusty Glock 19 (2nd gen) that I have carried since 1994, when I used it as an LEO.
