Cor! I am amazed not to have received any replies to this so far - I thought the air gun community would be full of suggestions of shops with a servicing department or that I might even get offers from members who would do the job themselves for the price of the parts and a cash bonus.
Am I asking the wrong question? Should the air pistol not be touched? Will the spring be just as strong as when new? Maybe I just need to dig out the seal at the end of the barrel and replace that?
Any suggestions at all??
