'FredC' - What's a 'Fish Snake'?

FWIW - I'm a Left-Handed writer, but, Right-Handed with tools, guns, and Sports.

With this bolt-action pistol, I would keep a constant Left hand grip on the fore-stock and work the bolt with my Right hand, (rotating the gun inward with my Left hand and 'bolt lifting' with my free Right hand).

This rig would actually work pretty good for me. It's kind of like working a 'break-open' shotgun or 'trapdoor' & 'rolling-block' action.
