My 79G is vastly under powered and leaking air. I have resealed it be it is no better. After looking closely you can see that the hammer spring and the valve spring are not original. Hammer spring seems too weak and the valve spring has been cut down and does not work correctly. I have bought a compression spring set but none will do the job. And I cant for the life of me find any spares. There is a hammer spring on the US fleabay but he does not ship to the UK.

Anyone with more knowledge on these pistols know of any where I might get something that fits?

thanks for the help
