here's a nice write-up on the .41 Special wildcat.
Most Needed Revolver Wildcat?
There is a niche for this round. It would be perfect in the Taurus Tracker. Plus it would be a great practice round for the big .41 mag revolvers.
Since i am on a .41 caliber jag, Ruger and Smith should offer a 4-inch barrel version of the .41. The GP100 would be a nice platform for a 5-shot model and Smith already offers their Mountain Gun in .44 Mag and .45 Colt.
