Ive bought a S&W model 10 4inch revolver a year ago at a gunshow for 170 bucks. I traded it for a colt 1911 .45 that my dad gave to my brother like a year ago. my dads had it since the 80s and its a really good shooter. however while shooting it at a range, a piece wore out and piece right below the palm saftey broke. its fixable, but my brother was gonna sell it. i consider it kind of an heirloom so i traded my brother it for my model 10 (wich it also from like the 80s") its just once wen we got it apprased at a gun show, this guy claimed its hammer was from WW1, i dont remember why it said this is but i just couldnt see this gun sold to someone else. Was it a good trade?
