Hi, grandfather's estate gun. 4 screw, pinned 4" barrel.
Serial C1061xx on bottom of frame, under left grip, cylinder and left grip.
Model number and age?
Thanks,
Another option if you don't want to buy snapcaps is punch out the primer from spent shells and fill the primer opening with RTV (silicone sealer).
Anything to absorb the impact, even if only a little.
Generally, dry firing the hammer mounted pin type will cause premature
wear of the bushing and pin.
The frame mounted type is probably ok, as the pin doesn't have to pivot
through the bushing.
Use spent cases with the primer punched out and filled with RTV to absorb
the impact. Cheaper than...
