Meet the Glock 22: The Best .40 S&W Gun Around?

The Glock 22 is considered by many firearms experts across the land a top gun. But just how good is it? Don’t let the model number trick you into thinking that the Glock 22 is the gun to take to the range to do some plinking. Due to the Austrian firearms manufacturer’s perplexing and even confusing method of determining model numbers, it would be easy to think that the G22 is chambered for the popular and low-priced .22 LR cartridge.

It isn’t. The Glock 44 is what you have in mind for the firearm to start or enhance one’s shooting experience.

The Glock 22 is actually a full-size service pistol, and is chambered for the powerful .40 Smith & Wesson pistol cartridge – the standard law enforcement round that was developed to provide “proven knock down power.” The round was developed jointly by firearms manufacturers Smith & Wesson and Winchester and was designed to duplicate the performance of the Federal Bureau of Investigation’s (FBI’s) reduced-velocity 10mm Auto cartridge.

Enter the Glock 22

The Glock 22 first appeared in 1990. It was actually the sixth handgun produced by the Austrian firearms maker, which numbered its products based on patent numbers. As noted, that certainly has caused confusion over the years.

It is a full-size version based on the original Glock 17 that was introduced nearly a decade earlier. However, the pistol uses a modified slide, frame and barrel to accommodate the differences in size and power of the .40 S&W cartridge. The standard size magazine of the Glock 22 is 15 rounds – while there is an optional 17-round extended magazine also available.

The firearm was designed with law enforcement in mind, and by 2006 became one of the most popular pistols, favored by military, police, security, and private citizens around the world. It has successfully bridged the gap between the .45 caliber and the 9x19mm Parabellum cartridge.

The pistol features the tried and true ergonomic Glock style grip and trigger that is set within a thick trigger ring with a forward finger rest. The sights are located forward and aft. Action of the Glock 22 is recoil, while it has an overall length of 7.32-inches (186mm) with a 5.43-inch (138mm) barrel. Said barrel features right-handed, hexagonal rifling with 9.84-inches length of twist (250mm). Unloaded the weight is 22.92 ounces, while fully loaded it comes in at 34.38 ounces.

The Glock 22 isn’t the only model chambered for the .40 S&W cartridge. The Glock 23 is a compact version, based on the Glock 19, while the Glock 24 is the long-slide variant, and the Glock 27 is the subcompact model. Glock also produced a competition version as the Glock Model 35, which was also used as the service pistol of the Kentucky State Police until 2017.

What is also notable about the Glock 22 – as well as the models 23 and 27 – is that they can be easily converted from .40 S&W to .357 SIG chambering by reducing the barrel. No other parts are required, and the .40 S&W magazines will also feed the .357 SIG rounds.

    Nice gun that firearms instructor’s will tell you it will not hold up to the recoil. It will tear itself apart after many rounds.

        Any handgun, Glock included, will have over pressures if the same round is ejected and rechambered repeatedly.
        This has resulted in dangerous detonations.

          When the article mentioned:

          “proven knock down power.”
          And the Federal Bureau of Investigation, with an Obsolete reference to 10mm, there is the rub, when the FBI stated categorically that after much research both with modern ammunition, the .40 S&W and 20 mm are indeed Overkill, for run of the mill Agents.
          Jeff Cooper was a huge fan of 10 mm calling the other, .40 Short & Weak as a sort of inside joke.

          I have loved 10 mm for Hunting with a Glock 20 and an extended barrel.
          But for example everyday carry, I find a Glock 17 (9mm) quite sufficient as there is little gain over .40 S&W orv10 mm, with a detail such as recovery time is accounted for and with 17 rounds ➕ 1, plus ➕ two for 20 rounds or a 30 round magazine option, for when the Devil comes to Breakfast.

            Sorry Mates, that should have read 10 mm and not 20 mm, there was no edit feature.

    The article appears to have been plagiarized from wiki by an eighth grader trying to finish a school paper for Monday morning, complete with “ chambered for the .30 S&W cartridge”. Never attempted to answer the original question “the best .40 around?” As to the comment above, i have put THOUSANDS of rounds through both my Glock 23 (gen 3) and my Glock 27 (gen 5). They are designed to handle all the recoil and more. The only issue I ever had is when I reloaded my own rounds and doubled the grains of powder (9.5 grains) and overcharged the extractor. Other than that my 14 Glocks are flawless in performance.

      GLOCK is overrated, the Springfield XD, XDM, or XDS is far better in my book, it’s up to the individual as to what’s truly better I find the GLOCK uncomfortable in my hands compared to the Springfield or even 1911’s. Never have liked the GLOCK….

      I’m glad yours are cause everyone I have owned has had issues, including the current one that has issues with the trigger not wanting to reset. I’ll stick to sigs. It sucks cause I really wanted to love the glock 20 in 10mm.

    @Paul How many police departments around the country have these as their service pistol? All the ones around here you’ll see it on a uniformed officers hip. Probably chambered in 9mm, but this is the first I’ve read about them not being able to hold up to being fired frequently.

    Please stop writing articles without doing any research.

      For My part l will stick to the 9m Glocks. To Me, shot placement means more than Caliber. A Glock is a very simple Gun which, as l see it, adds to Their reliability. I would like to have seen Glock stay with Their root Caliber.

    .30 S&W??
    How embarrassing. The entire article seems like it was written by someone Googled “Glock” but didn’t bother to read anything they found.
