Greetings people !! New member and first post here..... I have a question on a Glock 17 that I inherited about a year ago due to the untimley passing of my BIL. The serial # is BAC which I found on the date thread to be a 2nd gen. I am a gun enthusiast and own around 25 firearms, this however is the first Glock for me. I'm not a really big fan of the 9mm caliber and have a chance to trade this gun for a 3rd generation Glock 23 40 caliber which is more appealing to me personally. Upon sending pictures to the fellow who wants to trade he ask if the barrel had been changed because it is chrome and not black, I told him I did not know but all serial #s match,frame,slide and barrel. My question is were there any made with a chrome barrel or was this one polished after the fact. I would think it to be the original since the #s match. Any thoughts ?? Thanks W.G.
