I see model 10s and 64s prices all over the place on GB. It takes some patience but deals do come up.
I picked up a model 10-11 last December for 200+20 shipping a +20 ffl fee = $240
The pic below is how it arrived. I knew buying it the grips were tired. I have since replaced them with new old stock pachmayr. The gun is tight and is fun shooter.
Model 10’s with 158 grain LSWC were just made to be.
