I've bought and sold I don't know how many Model 10's over the years. I recently found myself without one, so I picked this one up to fill the gap.
10-11 from about 2000 I guess. Those three letter S/N's are a pain.
It's got all the "bad" stuff. Not pinned, MIM parts, frame mounted firing pin, round butt, new design cylinder release, and "goodyear grips." But it has a really nice trigger, and those "goodyears" are really comfortable. They also clear a HKS speedloader better than any other grips I've ever used. I don't think it's been fired outside the factory but can't prove that of course.
