This might suprise you
I think that some of the late production COLTS had some real problems. I bought a Det. special or what ever was the current Colt snubbie about 1996 NIB from a dealer. It was a blue gun. Looked OK outside. The bore was rusted right out of the box. So were the chambers. I scrubbed and scrubbed that bore with solvent and finally got the loose rust out, but then the bore looked dull and frosted, the rust had a while to work. New patches still got brown. Took it back and demanded my money back. Also got a blue special production Colt 45 auto a year or two before. It had a rusty bore right out of the box too. Got a S/S Anaconda later, in 45 Colt, as Smiths were about impossible to find in the cal. S/S, so no rust, but the machine work and finish looked kinda rough. Was not very accurate, and would only extract about half the cases, the rest slipped under the extractor. No fun to shoot a big bore long barrel revolver that is inaccurate, so sold it and swore off Colt. But just got a nice Diamondback from an earlier era (70'S) and it sure lives up to the legendary Colt standards. Back in the 80s had a Taurus 357 that looked nice and was smooth functioning, but the barrel was threaded into the frame so crooked, that the rear sight could not compensate! Shot 6-8 inches left at 15-20 yds! Went to the pawnshop for 60$.
