ATF Question

[Johnny Peppers]

The long barrel is not the problem, but the stock is. The only two German military Lugers that were issued with the shoulder stock/holster arrangement was the Navy and the LP08 Imperial Lugers. The BATF has classified these two pistols to be legal as a curio and relic with the shoulder stock as they were originally issued that way, but none of the other pistols were issued with a shoulder stock even though they have the attaching lug. As your Luger would be a converted pistol it would not qualify as having been originally issued with the shoulder stock.

That said, I have not looked at the regulations in several years, and someone may have something later than this.
