I think this just follows the general trend in CCW handguns. We reached size limits with both revolvers and semis, and things are bouncing the other directions as people just don't want to shoot their Glock 29s, Kimber Solos, and scandium/aluminum J frames stuffed with +Ps or .357s all that much!

I'm still focused on the bigger guns but eventually will stumble across a six shot S&W snub I just have to own.
