The 7mm Penna also known as the 7x23mm was developed by Fiocchi of Italy for the sport of competitive shooting especially for IPSC competitions. The cartridge became something of a novelty but was abandoned after a short time. 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. The 7mm Pena is a straight rimless cartridge intended for use in autoloading handguns. The cartridge produces little felt recoil which in turn provides quicker follow-up shots on the target.
