I guess we all know that.....
.....Cabela's and a lot of others sell stuff they call "1851 Navy" that has a lot of different descriptions that have nothing to do with Colt, or 1851, or the Navy, or the Navy caliber.
I don't like it any more than anyone else, but the name "1851 Navy" does not mean what it once did.
The name has been misused enough that when anyone refers to anything as an "1851 Navy" it is worthwhile confirming what they mean. Not in 19th century parlance but in today's.
I should have been more clear when I asked the question.
