Glock 22 .40 S&W Pistol: The Most Popular Police Gun for a Reason

Glock G22, A Short Review: Ever since Glock introduced their polymer frame pistols in the 1980s, their designs have taken the world by storm and proven to be exceedingly popular.

Glock G22, A Short Rundown

The Glock G22 is no exception. Glock claims that their G22 pistol is the “most popular police service pistol in the United States,” which if true, is easy to see why.

Though the Austrian gun manufacturer offers a number of calibers and frame sizes, this particular pistol falls in their Standard size category, a logical choice for a service pistol. The pistol is built around the .40 S&W cartridge, a high-performance pistol cartridge.

The .40 S&W gained widespread use as a lower-powered, more manageable alternative to the hugely powerful 10mm cartridge. And though the .40 S&W is lower powered than the massive 10mm, it offers significant advantages in energy when compared to the 9x19mm, though both cartridges have nearly identical accuracy.

Glock was one of the first manufacturers to offer pistols of any kind chambered in the powerful .40 S&W. Their rapid rollout was made possible by previously offering pistols chambered in 10mm, which uses the same diameter bullet as the .40 S&W. This was an early success for the company and vaulted sales forward.

The latest Glock G22 incorporates a number of the company’s Gen 5 updates, including a redesigned grip that foregoes previous Glock’s finder grooves, providing a better grip surface, and a redesigned slide design that has additional forward serrations that provide another tactile surface for charging the slide.

In addition, the G22’s metal slide is treated with Glock’s nDLC surface treatment, a coating that imitates diamond and offers excellent corrosion and wear resistance.

The G22 also retains Glock’s Safe Action safety system, made up of “three passive, independently operating, mechanical safeties,” that make Glock’s one of the safest pistols on the market.

Like other Gen 5 Glocks, the G22 is built around Glock’s Marksman Barrel, a barrel design that forgoes traditional rifling for a polygonal-shaped barrel. Glock maintains that this unique design allows their pistols a better seal between the bullet and barrel, resulting in less gas escape. Glock also says that bullets fired from their polygonal barrels also deform less, which translates into less wind resistance and better range and accuracy.

It’s not hard to see why Glock’s G22 design might be the most popular service pistol in the United States. Especially with their Gen 5 update, it combines everything that you’d expect from a Glock: a light-weight but robust polymer frame, an accurate barrel assembly, and Glock’s uncompromising commitment to quality.

    Did I time travel 20 years into the past?

    And glock wasn’t one of the first. Glock was *the* first to offer a production .40 for sale.

    The Glock 22 beat the 4006 by about a week due to Gaston “borrowing” a .40 round from Smith’s booth at SHOT and having the 20 rebuilt.

    The .40 offers a fair bit more bullet mass and energy than any 9×19 cartridge in the exact same size envelope. It is also considered a better “stopper” as a result.
