You got a good son in law Spirithawk!
Never owned one, but from what I've heard about them they were a quality, well-made revolver.
They were also chambered in .44 mag, .45 Colt, .357/9mm combo, .45 Colt/.45Auto combo, and .44 mag/.44-40 combo (according to my Gun Trader's Guide). I had never heard of the combo chamberings before so I'm thinking those versions would be quite rare.
Should be a fine companion to tote around in the woods!
