Weight
The G21 weighs 26.28 oz. empty and 38.28 oz. loaded. The G23 has an empty weight of 21.16 oz. and a loaded weight of 31.03 oz. (with a standard 13-round magazine).
Dimensions
The G21 is 7.59 inches long, 5.47 inches tall and has a width of 1.27 inches. The G23 is 6.85 inches long, 5 inches tall and 1.27 inches wide.
Line of Sight
The line of sight (distance between the front and rear sights) of the two pistols is distinctly different. The G21 has a longer line of sight of 6.77 inches compared to 6.02 inches on the G23. The line-of-sight distance influences the aiming accuracy of the pistol; generally speaking, the longer the distance, the greater the accuracy.
Magazine Capacity
The standard magazine capacities of these two pistols are both 13 rounds. The G23 has two higher capacity magazines available--a 15-round magazine and a 17-round magazine.
Glock "C" Models
Both of these guns are also available as "C' models. Glock "C" models have slits cut into the top of the barrel and the upper receiver; the slits compensate for recoil by channeling gases upward. The "C" models are designed to keep the pistol on target during rapid fire.
