Right now I own 8 DX models and several standard models, all my DX's will print under one inch at 25 yds with almost any load thru it. Probably my rareist is the 5 inch 629 and 5 inch 29 DX. Those will always stay with me. My understanding is that when the guns were test fired at the factory the ones that shot exceptional groups were dressed up as DX's. Im sure you'll love your gun, happy shooting!
