I usually go with the G27 for primary, but there are a lot of new guns out this year really aimed at CCW. Two tops on my list are a Taurus 905SS; 5 shot moon clip 2" revolver in 9mm, and a Kel-Tec P3AT; .380 almost the same size as the dimunitive P32. These both should prove to be good deep cover and BUGs.
