OK, I'll use an analogy to help clear this up.
In 1863 Colt was producing PISTOLS. They were Cap & Ball revolvers that were loaded from the front of the cylinder. Powder was poured in the cylinder, followed by a wad and then the ball. A percussion cap was then placed on a nipple it the rear of the cylinder.
In 1873 Colt introduced the Peacemaker. It was (and is) a revolver loaded from the rear of the cylinder via a gate. It used self contained cartridges and a bored through cylinder. It was (and is) called a PISTOL
1911 Colt introduced the Model 1911, commonly called the Colt 45 or Government Model . It is a semi-automatic PISTOL. It has no cylinder and uses a magazine (clip) to feed the cartridge. It was (and is) called a PISTOL
Skip ahead to the introduction of the Glock line of handguns. They're produced with polymer frame, not steel. They were (and still are) called PISTOLS
As a further note there are Single Actions PISTOLS, Double Action PISTOLS, Single Action Semi-Automatic PISTOLS, Double Action Semi-Automatic PISTOLS, Full-Automatic PISTOLS, but they are ALL PISTOLS.
SBC is a generic term similar to PISTOL.
Hope that helps put this issue to bed.
