Dear J&G Customer,
It has come to our attention that a small percentage of the available surplus 7.62x25mm ammunition has weak case heads. When these cartridges are fired in our new 1911 barrels, this combination can result in a case head failure. In order to avoid this, we recommend our barrels not be used to fire surplus 7.62x25mm. Modern commercial 7.62x25mm ammunition is acceptable for use in these barrels.
Our barrels have been redesigned to also allow the use of most surplus ammo. Any one who wishes to exchange their current barrel for one of the new upgraded barrels should contact myself, Kristofer Gulbrandsen, the gunsmith at J&G Sales. The next batch of barrels is several weeks from completion, however anyone desiring an exchange will be given preference over new orders.
