I know of one dealer who would not update his site to remove sold guns because he felt it gave him a chance to sell another gun when you called about one already gone. Not saying that's the case here. Perhaps they just don't update often because they don't want to pay extra for frequent IT services. Perhaps only updating sold items once a quarter but adding new items once a month. Seems silly but money if you can't do it in house you have to pay for others to do it for you.
