I recommend a heaping scoop of caution on this purchase. Most everyone knows that 28 bore M-12's are valuable. SOooo, the chances of a bargain are remote. If you can buy it like it was a fake and use it for a shooter, fine. However, if you are going to pay anything for origanility, make sure it has an unaltered serial that "books" for a 28. Take a look at the serials under high magnification and strong light. If you get pressure to buy it, run, don't walk, unless it is priced as a shooter.
