zip 22
A handgun chambered for .22 caliber rounds produced by the US Firearms Manufacturing Company (USFA), which prior had been known for its high-quality Colt Single Action Army replicas.
The Zip .22 was intended to be the "world's safest gun", but proved disastrous between poor ergonomics, extensive feeding issues, and needlessly complex operation. The gun's failure would bankrupt USFA while the weapon itself would become the butt of jokes among firearms enthusiasts everywhere.
