i remember my first go with a PCP, which happened to be a s410k,and i thought it was underpowered.it had no recoil and was very quiet,which made me think it was a bit of a toy.when i checked it on a combro,it was producing a consistent 11.6 ft lbs.are you sure you're not thinking the same way i did ? the airsporter will seem more powerful because it recoils and makes more noise.i havent got a combro anymore, so i cant help you with that.you could take it to sandwell field sports, which isnt too far away.
