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…

Left grip panel removed.

The latch forward of the trigger releases the barrel.

An e-clip (circlip, spring clip, etc) retains the barrel unit pivot pin.

Spring end.

Other spring end.

09291007

e-clip removed.

09291008

Pushing out the pivot pin.

09291009

Spring end

The spring is held in the barrel assembly by that pin, I’ll leave it as it simplifies things…

That panel slides back and forth.

Barrel clamp removed.

Plastic gizmo. I’m not sure what its function is as yet.

09291017

Looks like it is the detent for the rotary pellet clip?

More to come…

Any idea why this panel slides back and forth?
