7mm Penna

STI chambered a few of their Nemesis line of 1911 clones for this cartridge but ceased shortly thereafter due to very little demand for such a handgun in this chambering. This cartridge family also includes a 7x28mmR rimmed cartridge designed for use in revolvers and longer cartridges for use in carbines and rifles.
