This EB22 is just the nicest gun - especially with a set of Rick's grips. I post this for those of us (like me) who have/had no idea just the size of an EB22. It is pictured under my 1377 with RB Grips. It is easy to operate, shoots accurately and is just a blast.
(Yes, that is a heating pad under my guns. It is 43 degrees here in NC today and when I want to shoot in the garage that heating pad is the greatest!)
It never occurred to me to use a heating pad to keep my C02 pistols warm during the winter. Do you just get them warm and sit the pistols on the pad after so many shots?
Another nice C02 pistol is the venerable Crosman 150. It's a great size and balance and the dual-power setting is handy inside.
