Glock 19 is effectively a reduced-size Glock 17; it is called the “Compact” by the manufacturer. The Glock 19 has a shorter barrel (by about half an inch) and pistol grip compared to the Glock 17. Since it is a smaller gun, it is more popular for concealed-carry uses.
Both these semi-automatic pistols use 9mm cartridges and were designed by Gaston Glock. Another advantage of Glock 19 pistols is that they are compatible with Glock 17 magazines but Glock 19 magazines cannot be used in a Glock 17 pistol.
The Glock 26 is even smaller than the Glock 19 and is compatible with both Glock 19 and Glock 17 magazines. However, Glock 26 magazines cannot be used with Glock 19 or Glock 17.
The Glock 17 uses 9x19 mm cartridges. It is 186 mm (7.32 inches) long, with a barrel length of 114 mm (4.49 in) and a standard magazine capacity of 17. It weighs 625g (22 oz) when unloaded.
The Glock 19 is considered the “compact” style Glock. It also takes 9x19mm cartridges, but is only 174 mm (6.85 in) long, with a barrel length of 102 mm (4.01 in). It has a standard magazine capacity of 15 and weighs 595g (21 oz) when unloaded.
The Glock 19 pistol is compatible with factory magazines from the Glock 17 and Glock 18, with available capacities of 10, 17, 19, and 33 rounds. With the exception of the slide, frame, barrel, locking block, recoil spring, guide rod, and slide lock spring, all of the other components are interchangeable between the models 17 and 19.
The Glock 17 costs an average of $500. The Glock 19 is the same price with an average cost of $500.
