Magazine Capacity: Typically 13+1 rounds
Barrel Length: 4.61 inches (117 mm)

Why Choose a GLOCK 21 Gen 4?

Known for its reliability, durability, and simplicity
A favorite among law enforcement, military, and civilian shooters who want the power of .45 ACP
Good choice for home defense, duty carry, or range use (though it‚‚s a bit big for concealed carry)

If you‚‚re familiar with 9mm Glocks like the G17, the G21 feels like a beefed-up version—wider grip, heavier recoil, but with that same Glock simplicity.
