When giving the Colt a quick look in the display case yesterday it looked like a 3" barrel. After researching at home and finding no reference to a 3" I thought I may have been mistaken and may have been a 4". I went back and measured it today and it's a chopped 3". The top of the barrel is marked Colt A45 and the bottom was marked "United States Property." It has the screw hole for a lanyard on the bottom of the grip frame but no numbers there. Inside the yoke showed the serial number. The dull blue is in great shape and looks original. It locks up as tight as my 5 year old GP100s and tighter than a couple of my well worn model 10s. Since it's been chopped, doesn't have much collector value and priced at $695, I think I'll leave it for someone else. Thanks for the education.
