.45 ACP
The Glock 21 and Glock 21SF are both .45 ACP pistols, but the primary difference lies in their dimensions and grip design. The Glock 21SF (Short Frame) features a slightly shorter grip frame, which is designed to accommodate shooters with smaller hands for improved control and comfort. Additionally, the SF model has a reduced circumference in the grip, making it easier to handle while maintaining the same functionality and reliability as the standard Glock 21.
