I recently traded my original owner Glock for another one on straight trade. The gun was for a Gen 3 for a Gen 3 straight across the board. I was happy with the condition of the gun so I threw it in the box and throw it in my bag and drove home. Well, I had a lot going on and didnt have time to really look at the gun until a few days have passed. Well after I finally found a few minutes, I pulled the gun out to take it apart and inspect it and clean it as I always do. Upon me taking the gun apart, I realize that the frame/slide serial number do not match the freakin barrel number. I understand this is my fault but I am not one to tear guns apart in front of someone out of disrespect while trading and just "assumed" I was getting the same factory matching gun I was trading. Well my prediction.... Is it really that big of a deal? Should I just order a Lone Wolf barrel while ordering my conversion barrel for it or should I worry about it. Is it really that big of deal that I have a Mutt or shoud I just order the barrels and shoot the hell out of it? This is the first Mutt I have ever had... What do you guys think?
