RECEIVER PINS WORKING LOOSE

[B. Dudley]

That pin is the axle dor the sears. The hammers axle on two separate locked screws.

Likely whoever restored your gun felt it necessary to polish up the pin, thus reducing it’s diameter some.

You could try some locktite on it and see if it helps. If not, a replacement pin will be the only option. Or drilling and tapping for a fox style pin lock screw. But that is excessive.

My VH does the same thing. I'm going to try small thread Locktite but for the time being, I just keep an eye on it and tap it back flush when needed.
