Full Size vs Subcompact Pistols! What’s The Power Difference?
This video compares the velocity differences between self-defense rounds fired from a full-size pistol (Glock 17) and a subcompact pistol (Glock 43). The comparison uses a chronograph to measure muzzle velocities for several popular ammunition types, including Critical Defense, HST, Gold Dot, Critical Duty, Remington UMC, and Winchester. The data presented shows a consistent velocity drop in the subcompact pistol across all tested rounds, with deviations ranging from 65 to 82 fps.
