I have a ruger gp100 revolver stainless with a 4" barrell in excellent condition it has maybe 700 rounds through it I don't use it anymore. I also have a ruger P85 pistol also in excellent condition stainless with 3 clips that has 1000 rounds put through it and again I don't use it anymore. what I would like to do is trade one of them them for a plinker, I was thinking a Walther p22 so I could get my boy out there plinking at our club range here in connecticut and the price of ammo wont kill me to go out a lot with him. so which gun would I be better off trading in without getting screwed. I have no idea on what the 2 rugers are worth now. I paid $300 for each of them a while ago. eventually I'd also like to end up with a S&W MP.45 for myself but I have no clue at all on how much I should try to get to trade for a plinker and then a trade for the MP45 any thoughts would be appreciated.
