GLOCK LOVER says:I do not know anyone that carries the Glock 23 on their own time and their own dime. Practically everyone in my circle of friends and associates owns at least one Glock 19. The handguns are identical in size and shape and fit the same holsters. My yardstick, tape measure and calipers show that each is 7.35 inches long, about 5.0 inches high and 1.18 inch thick. They weigh but 23.6 ounces unloaded and pump up to about 32 ounces loaded. Neither Glock features a manual safety. The firing pin block and safety lever in the trigger are the whole show. True safety is between the ears.
