I have a Model 60 s/n R322xxx. I am an expert shot with my duty weapon Model 5903 9mm. I was an expert with my Model 66 6". But I am a crappy shot with the Model 60. The trigger pull is to tight and I cannot see the front sight when I shoot. I have no confidence in it, so I am thinking about selling it. It is in very good shape. Do you think I would be able to get $350 - $400 for it? Also, is this model a Pre-1980?
