Picked up an import 17L from a LEO friend of mine for $400 (Yes!). Would appreciate some help dating its birth. Couple of confusing features. Matching serial numbers (frame plate is shiny one). Serial nmber is CXL847, then on the barrel next to the SN is the little eagle, NPv EDD then a little pentagon shaped stamp. What I find a little confusing is the frame has the 3rd gen finger grooves/light rail but is only a 2 pin frame! It also has the eagle/NPv stamped into the frame just above the leading edge of the trigger guard. I'm sure there is no real reason for my confusion. Thanks for your replies. Wanna kill these ads?
