get it out and shoot, i like 230 grain ball for range and 230 grain golden saber for defence, really the gun should eat about everything u put though it,
In my Commander length guns, I find that the 185 gr loadings give a bit more velocity from the shorter barrel...try Golden Saber 185 or Winchester Silvertip 185. The Corbon Powerball loading in 165 gr looks promising also.
Combat Commanders were issue weapons for some deputies in Whitley county, I carried one until mine regular issue (full size series 80) came back from Colt. It ate anything and everything.
