When I first got into air guns, one of the first guns I got was a Gamo Whisper G2 in .22 (spring-piston). After learning more about air guns, I made the automatic assumption that gas-piston guns must be better in every way than spring-pistons. I sold the G2 and bought a gas piston gun, only to find it was less accurate. I can't find another G2 in .22.
