The Glock 33 is another subcompact weapon from the Glock family. It’s chambered in the .357 Sig cartridge and is visually almost the same as the Glock 32, except for the length of the barrel and grip. It is a good and powerful handgun great for concealed carry because of its small dimensions. The standard capacity of the magazine is 10 rounds. The Glock 33 Gen 3 features a textured polymer grip with finger grooves, lined front and backstraps, and notches for the middle and ring fingers, all in order to provide a secure handle for the gun. The pistol offers high muzzle speed and energy in a compact design, which makes it a great backup weapon with high-quality ballistic performance. The .357 Sig rounds are not as powerful as .40 caliber rounds, but they’re close. Some of the popular G33 upgrades are extended magazines (up to 34 rounds), slide lock springs, extractor depressor springs, etc.
