I had a Taurus 441 with a 3" and adjustable sights that was a good shooter, I'd expect the 4" version to be equally good. I had Ahlman's in Morristown, MN, tune it and ream the forcing cone before I ever shot it.
I've long thought that a K-frame 5-shoot .44 Special that was a mirror image of a 4" S&W 66 would be worth owning.
