Not an expert in barrels but this is my 2p's worth. *assuming its a 12 bore not needing any work.

.019 and .020 in its self would not be a deal breaker in a gun I simply wanted to own use and enjoy, in fact as you have alluded to it might mean a otherwise unaffordable gun is well priced as long as you shoot appropriate loads and look after it there is no reason why the gun wouldn't last your lifetime and perhaps longer again.

Thin barrels are inherently less strong, ie more prone to dents and should you develop a dent your more like to end up with a worrying thin spot.

Just don't convince yourself its an investment, its an indulgence.
