I think the longer barreled version is OK if you have a specific need for a lightweight revolver in this caliber and don't need a high level of concealment. ("casual" concealment rather than deep concealment...backpacking maybe, etc.) but I think the snub is a goofy idea. Why bother with something with so large an "envelope" with such a short barrel? With a CCW gun, the butt...not the barrel...is the harder part to conceal, and for range use that ultra short barrel and light weight will still make this a not-so-fun gun to blast with. Frankly, I would look for a nice, older, REAL M27, which could be bought for less money and would give you much better service and enjoyment. There was one in the EE a while back at a good price, but I do not know the seller. Or, if CCW is your goal, a "K" frame magnum or "J" frame snub.
