I've owned several early Kimber Classic Customs/Classic Stainless pistols. All had full length guide rods.
My experience with these early guns is that they shoot extremely well out of the box. Kimber was putting their best foot forward in these early years. My current as-built Classic Stainless held its own against every other higher end 1911 I've owned, some of which cost 4 or 5 times what I paid for the Kimber in 2000.
