I got an offer earlier today to trade my 642 in excellent condition for a 4 in. Ruger Security Six with hogue+original grips. The Ruger is about 90%. I have been considering picking a larger .357 for a while and was considering a gp100, but the ruger six series has had a pretty solid history. Just wanted to get a few opinions from more experienced revolver collectors before I do this even trade. Thanks.
