Glock

Since the release of the original GLOCK 17 in 1982, GLOCK pistols have become one of the most popular sidearms for law enforcement agencies, military forces, and civilian marksmen in the US and around the world.

GLOCK now produces several hundred variations of the famous handgun, now offering a wide selection of calibers, sizes, and designs. With so many options available, new gun-owners often agree that in current production the sheer number of different GLOCK handguns can be daunting.

Though GLOCK pistols share many features and aesthetics, each pistol is unique and has its own benefits. Even the same model of GLOCK pistol can have different feature sets as it evolves between generations, so it’s important to know the fine differences between the pistol models and their generational updates.

Currently, GLOCK manufactures semi-automatic handguns in eight different calibers: .22LR, 9mm Luger, .357 SIG, .380 ACP, 40 S&W, 10mm, .45 ACP and .45 GAP. GLOCK also offers 5 different sizes of handgun, and many calibers will have multiple sizing options: Standard, Compact, Subcompact, Slimline, and Competition.

There are also 5 different generations of GLOCK pistols, though the 1st and 2nd generation pistols are no longer widely available. The 3rd, 4th, and newer 5th generation pistols are all commonplace in today’s gun industry, and you will not struggle when searching for parts and information.

The 3rd and 4th gen GLOCKs have interchangeable backstraps, an enlarged and reversible magazine catch, a dual recoil spring, and a rough textured frame to enhance grip traction.

The ‘MOS’ is GLOCK’s Modular Optic System.

With MOS pistols, you can attach a wide variety of mini reflex sights using GLOCK’s specially fit mounting plates. This makes it easy and cost effective to add an optic to your pistol, since you won’t have to pay a specialized machine shop to cut your slide.

The GLOCK 19 is a semi-automatic, polymer-framed compact handgun. The GLOCK 19 occupies a very special position where it’s small enough for concealed carry but big enough to achieve match-grade accuracy and quick double taps. It’s lightweight, accurate, and simple to clean and maintain. Owners can service or replace any part with minimal tooling or experience. Combine this with a relatively affordable price, and you have a pistol which is poised to be an American favorite.

In many ways, the GLOCK 19 is GLOCK’s ultimate ‘do-everything’ pistol. It has tremendous product support both from GLOCK and aftermarket manufacturers. Pretty much every holster manufacturer will provide an option for a GLOCK 19.

Though other pistol manufacturers offer similarly sized 9mm handguns, the GLOCK 19 remains a standout performer in a world of polymer striker-fired pistols. Whether you’re a first-time buyer or an experienced professional, the GLOCK 19 has earned its place in your collection.

Ultimately, the best pistol will vary depending on your body type and preferences. If you’re smaller, you may have a harder time concealing a full GLOCK 19. Likewise, if you wear thin clothing, a full-size pistol will probably print under your garment.

In general, we recommend shopping among three categories: Compact, Sub-Compact, and Single-Stack.

Compact GLOCK pistols like the GLOCK 19 are a common choice for concealed carry, particularly with appendix carry. These pistols offer improved control and capacity when compared to the smaller sub-compact or single-stack pistols, but it comes at the cost of weight and size. If you’re petite or want to wear tighter/thinner clothing, a compact pistol may not be the most concealable option.

Sub-compact pistols are even smaller than the compact models, but their double-stack design means you still conserve an acceptable capacity. Pistols like the GLOCK 26 are very popular for concealed carry—especially for those who want minimal intrusion or weight on their beltline.

The easiest pistols to carry are the slim single-stack pistols like the GLOCK 42 and 43. These sub-compact, single-stack pistols are the smallest GLOCK pistols available, making it easy to carry in any outfit. Be aware, though, that size comes at a compromise. You’ll have more recoil, less accuracy, and a limited capacity, but if you want the most comfortable pistol to carry, the GLOCK 42 and 43 pistols can be a dependable lifeline when every moment counts.
