Take a chance if you find something you really like and want and the price is right.
( consider FFL fees into the price)
I bought a surplus from Danger Close Tactical that was a ugly duckling but I really wanted it.
Model 10-2 Military and Police, Double Action, 4" Tapered Barrel, Blue Steel Finish (worn), Surplus, Import markings "AA280", ."JP1712" D63xxx Year of manufacture between 1969-1970. ($250. It’s still on his website listed as not in stock)
More import markings than my passport.
More worn than my favorite jeans.
Almost won Inspector’s fun shoot with it but they didn’t count surrounding the target.
(At least I didn’t come in last though. Got 1/2 a point for hitting a different target

)
I love that gun. (But don’t shoot plus-P out of it.)
I did get to check lock up and alignment before I bought it though.
