When introduced in the 1990s, the FN P90 PDW was far different from more traditional carbines with its design and chambering. It design and layout are truly unique, and even two decades later the semi-automatic PS90 is still popular and futuristic.
With a double- and single-action and built-in de-cocker, the Beretta 92FS has been a popular semi-automatic 9 mm handgun since its cousin, the M9, was adopted by the U.S. military in the 1980s.
The popularity of small-caliber pocket pistols chambered in .25 ACP and .32 ACP has waned considerably in recent years due to an ever-growing selection of sub-compact models chambered for larger cartridges, including 9 mm Luger and .380 ACP—a transition that occurred, in part, due to the 2008 release of Ruger’s Lightweight Compact Pistol (LCP).
Since its acceptance for use in the service rifle class of competition by both the DCM and the NRA in 1974, the .308-Win.-cal. M1A and, to a lesser degree, other such M14 clones have risen from obscurity to ubiquity in the hands and minds of shooters ranging from Vietnam vets to ranchers to highpower rifle competitors.
Having a long gun that accepts the same cartridge as your handgun has made good sense for 150 years, but some of today’s modern pistol-caliber carbines take the idea a step further by sharing the same magazine.
