I want to see if you can help me decide on which revolver I want. Its between a 10-5 and a 15-3. The prices are $340 for the model 10 and $460 for the model 15 which I think is high for the 15 because both are in about 75% condition. I originally wanted a model 10 for the price (I heard i can get a shooter for around $300) but in my area they are a lot more and there is no police trade ins online right now. Then I saw the the 15 and thought about it and what price do you think I should try to talk him down to for a good deal? Are the adj. Sights worth the extra money?

Thanks
