i've posted this on other forums, and had pretty much one answer from every one. i tried last night here but kept getting a error message, but now i'm here so i'll post it. i have a friend who wants to trade me out of my ruger sp101 357 mag., he is offering a choice of taurus tracker's 44 mag. he has had the guns for about 6 months, i've had the ruger about two months, he said he's shot only about 200 rounds thru each one, i've shot 50 rounds thru the ruger. he's got two tracker's a 2inch barrel, and a 4inch barrel, he wants my ruger and 100 rounds of ammo for the 2inch barrel tracker, and the ruger and 200 rounds of ammo for the 4inch barrel. he says the reason for trading is he's got two 44's and just want to get a 357 mag. should i trade?, thanks for any help.
