Furthermore, some 1911 Fans are just plain snobs who act like anything that isn't made by Colt isnt a "real 1911"...
And some of us are real snobs who think that the only "real" 1911s were made by Colt, for the US government, between 1911 (year of adoption) and about 1922-23 when they 1911A1 replaced them on the production line.
And we feel that the guns Colt made for the commercial market are not 1911s or 1911A1s, either, they are Colt Government Models, which is how they are marked.
Call them whatever you want to call them, guns are what the maker designates them as. Shorthand versions of name work in casual conversation where the subject under discussion is well understood by all parties involved, but when things turn to technical aspects, using the incorrect, or incomplete terms creates confusion, because some things with very similar names (and identical "shorthand nicknames) can be quite different in their technical aspects.
My son has a S&W 1911PD. Its a great gun. You might call it a 1911, S&W does, sort of, its a 1911PD. I call it a S&W 1911, to be sure to differentiate it from the actual 1911 military pistol.
Now if you really want to get confusing to many people look at Ruger's Vaquero and New Vaquero. Nearly identical names, quite different guns.
You may say "what's in a name?,,," and often in general conversation it doesn't really matter, but when you go to order parts, or discuss technical aspects, the correct name really does matter.
Say 1911 pattern or 1911 style guns and I get an idea what you're talking about, Just say 1911 and to me, you're talking about a specific historical firearm not the type in general.
