Depending on my mood I accessorize with whichever piece best matches my shoes and belt.
Okay I jest. I don't carry every day although recently I've started carrying more than I dont.
When I do I usually take an LC9 with me most of the time. Got my wife the new LCP II .380 when it came out a few months ago and I carry it as well. Small, really light and easy to conceal.
My favorite carry was/is my Colt Mustang Pocketlite .380 in stainless with Pachmyar grips. But I rarely take it out because I worry if I shot someone I'd hate to have to give it up. That'd piss me off.
All of them are single stacks but I always have two mags full of Speer bonded jacketed hollow points. I figure if I can't hit a mugger with 12 shots I deserve to go down.
