Gamo PT-80 Disassembly, Part 1

A kind reader of the blog sent me a Gamo PT-80 pistol to mess around with. The CO2 cartridge seal was damaged and it may have other problems. First step was disassembly. The main function of this blog is to provide a record of what I’ve done so that I can successfully reassemble my projects, so this is going to be a bit detailed. The PT-80 is a complex mechanism…
