Just read your freview on the CFX.
Noted your "tweeks", & at resonable cost too!
Concerning the "twang" of the Gamo Shadow Sport, as we previously discussed, I think that as the plastic/synthetic stock is less solid & lighter than the CFX stock, me thinks it is a lot less effective at absorbing the "twang" & recoil.
The other week I was talking to the chap at the place where I bought it from & he told me that it, the Shadow Sport, could do with a piston guide, or was it a better piston guide. Can't remember now exactly what he said. Will have to enquire the next time I pay a visit. Is it possible that this rifle has no piston guide? Apologies if I am talking cr*p. Still new at this game.
Far too many rifles & pistols to mention here.
