I have a Lawman MKIII snub myself. They're an interesting gun. The only other people I've talked to with them tended to use them as working guns. The Revolver Armorer in Suffolk VA can work on them. The general advice was old timers was that the MKIII snubs were durable guns and would take a lot of full power magnum ammo without problems, but could break firing pins if dry fired extensively without caps. The snubs use a different grip than the regular ones, so replacement options are limited, but mine wears Colt logo rubber ones gifted me by another forum member. I also have a set of custom limited run wood boot type grips for mine.

These guns seem to be a bit of a forgotten gem. I didn't know that they were that sought after. They're interesting to handle alongside a DS, since they're somewhat like a bulked up DS I suppose, though more akin to a K frame snub in terms of size.
