9mm, with 115 gr. +P loads.
Until last summer, I didn't carry. And we were mostly in condition white. But then a drug dealer moved in right across the street in our nice suburban neighborhood. My house gun at the time was a Dan Wesson .357 with a 6 inch barrel (using .38 +P's).
Last summer I got the concealed permit and a Kahr K9 to carry in a fanny pack. But as fall came and I could start wearing a jacket, I got a Ruger KP95DC and have carried that, both in OWB and lately in a IWB holster. I like it more than my Kahr! I'm just hoping I can find a way to conceal it this summer.
By the way, the city LEO's helped us get a neighborhood watch going, and combined efforts got the drug dealer out of business. And my wife and I are making efforts to stay in condition yellow.
Stay safe!
