The frames are numbered after they are cast and way before putting the gun together. I know of a high 300 serial number that may not have been delivered but it is on the frame. Remember, sales essentially started at the end of september and your PIF is only 20 or so days into the ordering. This does not count the ones that are deposit guns. I think 2000 is a reasonable number considering IMO that heavy ordering was going on here on the BBS through December of 2005. The guns being delivered to non BBS members are not reported here either.
