Wow! I had a Uberti 1873 Cattleman SAA in .44 Mag and they have parts for it. However, they don't have .44 Mag barrels and cylinders. Maybe they stopped making them because they had a tendency to rotate viciously. I had a mashed pinkie from the wrong grip a couple of times. They still have .44 Special barrels which would work but the .44 special cylinders would be a little short. I know that they're strong enough because they still have .357 Mag parts. Anyway, way cool! Nice link Mike!
