Eventually, it was decided that it was more trouble than it was worth, and while America's first general-issue rifle musket (as well as a shorter rifle and pistol carbine
), the Model 1855 Springfield, incorporated the Maynard tape primer, when the gun was updated in 1861 the doctor's contrivance was jettisoned and the new Model 1861 Rifle Musket was set up only to handle the more common percussion cap.
Perhaps the pistol carbine most familiar to American firearms enthusiasts is the quick detachable stock for the single shot Springfield percussion .58 caliber Model 1855 used by the U.S.
Hera-Arms used a 1911 frame with its alloy upper receiver, bolt and barrel to create a pistol carbine on which various accessories could be mounted.
However, semi-automatic pistol carbine designs came and went until the 21st Century when they again appeared on the scene, but this time they were often in the form of polymer and metal skeletons in which pistols were housed.
It may well bring about a rethink of the many 9mm AR and other pistol carbine platforms now on the market.
Even an X01 in the trunk of a marked police vehicle might make an excellent backup "pistol carbine" or SBR.
