When it comes to Galco Holsters I have a strong recommendation, stay away from the Wheelgunner unless it would strictly be used for range work.

I have one around here somewhere that I picked up for my 4" 686 SSR and it is one poorly thought out design. It's not stable in any configuration and they should have included a slot to tuck in the tab that holds the gun portion of the holster to the belt portion. That tab is just waiting to catch on something & come undone and when it does the gun and the gun portion of the design is gonna fall out.

This is a design that tries to fill more than one role, strong-side & cross-draw, and does neither well.
