Thanks Rich and Muk. They are Uncle Mike's Boot Grips.
Although I have a number of handguns, I only use three for concealed carry...the S&W snub, LCP, and a Colt XSE Lightweight Govt. Model. I have three holsters for each gun. What I carry out on the street depends on how I'm dressed and the weather. I carried the Model 37 snub for 16 years before I bought my LCP over two years ago. It's hard to believe I've had a concealed-carry permit for 21 years now. Hanging out at the house though, I'm only packing one...usually the LCP or the Smith. The Smith & Wesson has held up pretty good over the years, considering I carried it so much. Like most of you, it's very hard to say which is my favorite handgun...because I like them all!
