I'll agree with RA, but I think sniper hit it right on the head. What the public sees on TV and in the movies are what drives the market. When was the last time you actually saw a wheelgun in a movie or on a TV show? There may still be a few of them on the silver screen, but not many at all. As for them being "limited"? I personally don't think so. Gunshops around here still carry a good selection of them from Smith, Ruger and Taurus.
