They haven't been U.S. military issue for 35 plus years. Any of 'em that were surplused, are long gone. Any that are still around in decent original condition are worth an enormous pile of money. (Last price I saw on an issue 1911 was $2500 US, Stateside. Cried for an hour. Had one I had to sell to pay a lawyer. Issue holsters are worth a lot more than you'd think too.) Lot of 'em got turned into IPSC/Pin guns/other race guns.
Governments don't sell surplus firearms much anymore either.
"there 1911" Where?
