I have been wanting a Ruger GP100 with a 3" barrel for quite sometime although I don't know how much I will shoot it. I already have a 4" barrel and hardly have any rounds through it and I have had it over 20 years. Our gun show is coming this week end and I thought I would take my Remington 760 pump action 30.06 to the show and try to trade it for a used GP100. I would like to have one with adjustable sights and the Hogue grips. My rifle is super clean although no glass on it and not much wear on the slide. Do you think I can trade about evenly or should I just leave the 30.06 in the gun safe? I have 3 .45's and 1 9mm plus my GP100. About the only thing I shoot is .45 and I do that weekly so it may end up being another safe queen. Any thoughts?
