The primary advantage of a carbine over a pistol using the same ammunition is controllability. The combination of firing from the shoulder, longer sight-radius, 3 points of contact (firing hand, support hand & shoulder), and precision offer a significantly more user-friendly platform. Carbines like the Kel-Tec SUB-2000, Hi Point 995TS, Just Right Carbines (JR Carbine) and Beretta Cx4 Storm have the ability to mount user friendly optics, lights and lasers thanks to them having accessory rails, which make target acquisition and engagement much easier.
