One of the problems I have with this type of firearm is the designation. I often get a caller asking for a "1911 xyz". My answer is I do not have it. He will then say something like "It is on your web site" or "You had them at the gun show".
That makes me realize he does not specify which model and I then answer that I have only 1911A1 xyz's.
My guess is 90% of the time a guy is speaking about a common everyday commercial or a more available WWII version, he will refer to it as a 1911. In the minds of most of them today, everything is 1911.
I have the same problem with the 03A3.
