m1991

I take it you are talking about the M1911 pistol which is the BF3 veteran weapon and your veteran status is coming up as a zero correct? The easiest way to automatically update your veteran status is to play the Battlefield games while logged in with your Origin account - this will automatically update your status.  The veteran page here http://www.battlefieldbadcompany2.com/veteran is the next best way to update the status manually, for newer PC\Console releases it will automatically update when you hit "refresh veteran status" or play the games while logged in with your origin account.  On the lower part of the page you can enter the CD keys for the older PC only games by clicking on the game's icon.  You can also update the game expansions that do not contribute to your veteran status by selecting the expansion like Euro Force and then entering your Gamespy ID and password.

Anoter way to unlock the M1911 pistol is to go here:  http://gunclub.ea.com/us/mygunclub and sign in with your origin account that you are using on Battlefield and you will get access to the M1911 via the EA Gun Club promotion.
