EWKarms has everthing ever wanted for a DW revolver to keep in good shape or to upgrade. The Hogue grips if the soft rubber version work well to aid control and if prudy grips are wanted LB customs can cover that need.
You will be buying one fine heavy shooter with the DW 44mag.
I can't tell you anything about a cash difference as our Lgs is one of the lowest priced dealers around on new firearms. The blued SA loaded they have sells for $760, SS is 800 .
