I suppose it must depend on what part of the country you are in. I try to "make the rounds" in the northern Az. area LGS's and gun shows, looking for pre-lock S&W revolvers and Colt handguns pretty regularly and the "L" frames (586/686) are what I run into the most often, followed by "J" frames. I own, have owned, or have been issued at least 22 of these (586/686) models. Before the Glock 22 took over the LEO market in the west, the L-frames were extremely common LEO weapons and there are lots of them out there. Ironically, I have a hard time finding clean "K" and "N" frames for reasonable prices in this area. The 2.5 inch 686 and the 696 are the only "L"-frames I don't often run across.
