Okay I bit the bullet and purchased the Colt!
Had the Colt, Glock and Ruger laid out on the counter and after much
discussion bought the Colt. Won't be able to bring her home until Tuesday though.
Anyway, it is a M1991A1 and I've been trying to find a site I can look up the serial number, any idea's? ...or do I have to call Colt directly?
