I was wondering if anyone knows of a Ruger Mk III / Mk IV magazine configured for .22 shorts. Not looking / expecting them to cycle, just line up so I can hand operate the action without fumbling. The ammo would be .22 CB caps and the purpose is executing pests in the yard at real short range. I've got a 10/22 magazine which was either built for shorts or converted to shorts and it works well in the rifle. I'm looking for a handgun equivalent.
