I got a 80's blackhawk .357 mag in stainless. The gun has the usual skuffs, but overall very nice. I taking it to my gunsmith for some internal polishing (I do the work, he just guides me). The biggest question I have is the front sight. I know I'm not a target shooter. But the sight is a little loose. Seems to wiggle back and forth and side to side. Is this normal? Or something that needs fixing.
