I recently purchased a Colt Detective Special, and am finding myself using it more and more for CCW.

Previously used a S&W 340PD, but I can't shoot the 340 nearly as well as I can the Colt. In addition, the 20 oz Colt with its bigger grip is fun to shoot at the range, whereas the 340 is just painful.

Also experimenting with a Glock 26. It shoots well, but so far I haven't been able to find a holster or carry technique that its comfortable for all day carry.
