Is the JRD prefix on the serial number that much more desirable? I found one of them & also one with a UCX prefix. The UCX is about a $75.00 cheaper deal. It comes with two magazines & is complete, box & docs, lock & spent shell, & is factory new. The JRD has one magazine, box, no docs or lock, & has maybe a box of bullets run through it. Which do you all think would be the better choice? Any help is vastly appreciated!
