My grandfather passed a year ago and left the family with numerous guns. I was asked to go through them and pick out ones I want with no intent to resell. I settled on a Model 60-7, which was in great condition, good timing, no endshake. I have carried it this summer after my PPS got stolen and I'm thinking about having some work done to make it more suitable for the role. Particularly having the hammer bobbed, and converted to DA only but I am not particularly familiar with revolvers, so would this be a bad idea for any reason? Is there anything else I should look to have done? And who ought I send it to?
