Mk Iv?

[dadofsix]

I see this designation quite a bit and never thought twice about it until now. Can anybody tell me why Colt uses the MK IV designation and what it means?

<><Peace

I don't know where it came from, but i can tell you that it was used on pre-1991 Series pistols, and as far back as, at least, the beginning of the "Series 80" and even on some late "Series 70" pistols as well.

Although the MK IV is well know, I would suggest you go to your library and find a book by Charles W. Clawson called "Colt .45 Government Models (Commercial Series), Second Edition". Although I don't think there was ever a MK I there was a pistol that was before the MK II and it talks about the MK II and MK III models around page 100. If you are interested in the 1911 this book is worth the read.

My library, a gun book, hah!

What IS a Mk II?

Colt used Mk III on both the 1969 coil spring revolvers AND the last version of the Gold Cup .38 wadcutter mutant. Was Mk II the previous .38?

Mk IV Series 70 was of course the designation for the 1970 Accurizor bushing guns.

Mk V was the next go-around of coil spring revolvers like the King Cobra.

Yuk yuk, and I have a Colt Trooper Mk III revolver I bought in 1972 or so, but in the 1911 world the early "Mks" were the Colt Gold Cup .38 Special Mid-Range guns I think. The book is still good if you stumble into a copy and there are lots of pictures in it. I bought a copy at a gun show. I have seen one Mk III in .38 Special. Looked like a Gold Cup. Flat top rib, sight, trigger, etc.
