The selection of .22 LR as a common caliber for semi-automatic pistols is accurate due to its widespread use in various types of pistols designed for both sport shooting and recreational purposes. The .22 LR (Long Rifle) cartridge is known for its low recoil, affordability, and availability, making it an excellent choice for training new shooters as well as for casual plinking. Many semi-automatic pistols are chambered in .22 LR, allowing users to practice their skills without the higher costs or recoil associated with larger calibers.

Other options, while useful in their own contexts, do not typically serve as common calibers for semi-automatic pistols. The 12 gauge is primarily associated with shotguns for hunting and tactical applications, while the 5.56 mm is a caliber more commonly found in rifles designed for military and tactical use. The .44 Rem Mag, although a powerful cartridge used in certain revolvers, is less common in semi-automatic pistols due to its size and recoil characteristics, which are more suited for revolver design. Thus, .22 LR stands out as the quintessential caliber associated with semi-automatic handguns.
