I have a Gamo auto 45 that is a CO2 pistol for garden plinking at the moment, I nearly always use it single shot on pellets. Don't really like BBs.
I would like something more powerful, more range etc.
My friend has the Walther CP88 type pistols, and they don't quite do it for me
I know I'm not going to use it much over the 10m mark much, although I am very interested in using one at the 20-25m mark, sometimes in the summer we can do this, all I need to do is be able to hit a 6 inch pellet trap to be happy
Short list from the comments:
HW45
HW40 - maybe, are these more powerful than a CP88 or much the same?
Benjamin EB22 - maybe, but needs a nicer grip!
Not a Cometa Indian - don't really like the look.
Crosman 1377/22 - hmmmm, maybe this or the EB22 AND the HW40...
