The DW revolvers ruled IHMSA for years, and that client base helped keep them afloat. When silhouette shooting lost it popularity that client base, and all the free advertising in the slicks, dried up. I still own an 8" M45 and it is frighteningly accurate at 200 meters with a 300 LFN at 1080 fps. It is too big to carry for most hunting, IMO.
