i have a sig 229 .40 cal. non rail with a round trigger guard. i have 4 mags 2 holsters and have upgraded it with the short reset trigger and fiber optic sights. i was looking at a trade of a smith and wesson model 36 38spl. plus some cash. both guns are used, the smith shows alot more use than my sig also. I look the values up on the smiths and they go from 250-450 but when looking on all the sites i can not find one close to that price, they are all around 550-600. the guy is wanting to trade me the smith and 200 dollars and i dont feel it is a good deal. any input?
