I'm a avid shooter of pre-1950 pump and auto shotguns but have opted to pass on the Model 10 (and the 29). The gunshop I frequent has a couple of both in the back room as parts donors. Rep on the 10 is that are function finicky as a lot of moving parts have to be sync to work properly.
The one you are looking at might function just fine and you might get $175 worth of enjoyment out of it no problem.
Does the shop have some type of bullet trap? Couple times I've told my gunshop guy 'Yeah, I'll give you ______ for it, if you function test it and it goes bang two times in a row.
