Scandium alloy is a mixture of Aluminium and Scandium.

Those are Pachmayr Compac grips. I pocket carry that revolver in 5.11 Covert Tactical pants. Sticking is not an issue for me.

Hogue Bantams do not cover the backstrap, the Pachmayr Compacs do. Remember that by covering the backstrap, the distance to the trigger is also increased slightly. These grips are not for everybody.
