Prototype Pieper .45ACP Pistol

Nicholas Pieper designed a blowback pocket pistol which was manufactured under license by Steyr in 1908. It was a reasonably successful pistol, and can be found today in .25ACP and .32ACP calibers. This particular one is an experimental version scaled up to .45ACP, with the intention of making military or commercial sales in the US. One unusual trait it shares with the smaller versions is its lack of extractor – as a blowback design it will function without one, but the shooter must break the action open to manually remove an unfired cartridge.
