I have a pair of Hawes Western Marshall .44 mags, they're decent guns, nothing special. I used mine for SASS shooting because they were inexpensive and my rifle I was using was also a .44.
They're a bit bigger and heavier than a true SAA clone, and parts are supposed to be hard to come by, but mine have held up alright. I don't much care for shooting hot loads in them, it's unpleasant. I imagine a continuous diet of hot stuff would loosen them up, but it would take a bit. At the end of the day, it's still a 300 dollar gun, not a top end revolver.
