These are high quality, somewhat larger sized double barrel tip-up pistols with fairly large grips. They are made for some
hefty recoil cartridges, so the larger grips are more comfortable than little ones would be. Most of the grips use spacers of some sort, which you first sand lightly to fit into the frame cut-out nicely, and then epoxy glue to the back of the grip
panels with the panel held in place on the gun, one panel and spacer at a time. The oversized grips use a filler spacer that
is epoxied to one panel, and then small steel pins are fitted to matching holes in the other grip panel to make a snug,
secure fit when combined with the grip screw.
