I recently came across a S&W 1905 m&p (unknown serial# or date of manufacture) with 6" barrel, 85%+ condition, with plastic grips, possibly round butt and hand ejector. I did not inspect the gun because I was preoccupied with something else and I have no knowledge of the pricing on these pre-model 10's, but now the seed of doubt has been planted. Maybe I walked away from a good deal? I realize it's hard to price an unseen gun but the sticker was $195. Can anyone give me a fair range of values for these revolvers?
