Reply To: S&W 78G Piercing Pin
The piercing pin assembly for the Crosman Mark 1/2 will work in the S&W 78G/79G.
I was just given a S&W 79G that the seals are toast in the piercing assembly. Used the assembly from my Mark 1 to be able to shoot it. Fired gun 35 to 40 times. Gun had set for a long time gathering dust without being shot, so I ordered a seal kit and will reseal the whole gun when I get the kit. When I received the gun, it still had one of the old CO2 cartridges in it with the crimped on top hat. Thats why I know it had not been shot for probably several years.
Ziabeam, still would like to see your build instructions.
