Yes, some Rugers are highly collectable. Some discontinued models are selling for big bucks. IE: Hawkeye, 357 Max Blackhawks, Old SBH flattops, and many more.
One handgun that seems to be attracting attention now is the discontinued SRH in 480. I have noticed prices going up on this model.
I know this is a handgun forum,
but notice discontinued 9622s & 22Mag have nearly doubled.
