Recently I bought a consignment M36-1 at the local GS for either $350 or $375 (can't find the ticket). Seller wanted $400. I suspect prices might vary from region to region. This one was LNIB, except there was no box or papers. Anyway, I really like the 3" barrel. Downside is that it's no longer easily pocketable. Better in a belt holster.

I'd say $500 is too high.
