Thanks for the welcome, all. Took my CFP class with Dan Willoughby of Center Mass Firearms training this past weekend. Enjoyed it, learned a few things. I'm not in any hurry to get additional guns, the SR22 is likely to be it for a while, due to budgetary and other constraints. Yes, I'm sure it'll be carried concealed at some point (need the license first).
As for holsters, I bought a cheap ($7) Crosman generic air pistol holster for it just so I had something. It works, and fits fairly well, but I'm not entirely happy with it. The grip is more obstructed than I'd like when the gun is holstered. I'm sure I'll get something better eventually, but am not in a rush. Can't yet carry concealed, and my local range doesn't allow holsters.
