Some clarification:
During the past two years when I've stated the V-Springs were dead, it was in reference to the OLD V-Spring Colt actions dating back to around 1900.
The last two Colt DAs (MKIII & MKV) used coil mainsprings, and newer re-designed actions requiring almost no hand-fitting.
Last year I was told by a Colt rep that the new revolver would be along the lines of a MKV, which meant a coiled mainspring.
I did not press for further details because the project was a semi-sorta hush-hush & I had not pressed for details since.
Yes- the new Cobra does have a V mainspring, but this is NOT the same action as the older Python, original Cobra, Official Police, original Troopers, Detective Special, and so on.
It is quite a different action, without the hand-fitting involved in the older guns, and with other significant changes.
Nothing out of the older action will interchange.
You will not be able to buy new Cobra parts and use them as replacements in original V-Spring Colts.
DO NOT EXPECT AN OLD V-SPRING ACTION IN THIS NEW COBRA.
Hope that clarifies the V-Spring question.
