My Parker in an ammo can project made a major advancement this week when I was able to obtain a set of barrels that march well and I'm making progress fitting.

The gun came with the original roller hinge, pin and screw. The pin is really tight. The parts are clean and lightly oiled. I use a small brass hammer to tap the pin and then snug up the screw and then tap some more. At this point, I have just driven the pin in about half way - enough to work at fitting barrels.

How tight should I expect the pin to be? Does it require driving in? Should it be a slip fit?

Thanks!
