5 Best-Selling Guns of 2021: The FBI reported that there were 39 million federal background firearm checks in 2021, slightly less than in 2020, but still a staggering number.

As usual, that means gun purchases in the United States are incredibly popular. Some models of firearms stood out over others last year. So, let’s take a look at what the five best-selling pistols were in 2021.

Glock had three of the five best-selling pistols in America, according to The Glock 19 was number one, followed by the Glock 43 in second place, then the Sig Sauer P365 came in third and the Springfield Armory Hellcat and Glock 17 rounded out the top five.

Best-Selling Guns of 2021 – The Glock 19

The Glock 19 topped the competition last year. The handgun is not only hugely popular in America (introduced in 1988), but it is ubiquitous around the world. The Glock is easier to carry than other pistols of its class and this is what makes it so popular with law enforcement. It’s not the prettiest gun, but it doesn’t malfunction much. It is inexpensive and usually runs around $500. It fires well at close range making it fine for home defense. It carries 15-rounds in the standard magazine.

Best-Selling Guns of 2021 – The Glock 43

Need something for personal defense that is easy to carry? Look for the subcompact Glock 43. The double-action, polymer pistol with a six-round capacity is known for reliability and accuracy. It’s also relatively easy to maintain. It fires a single-stack 9mm round. It is just over six inches long and weighs only 22.4 ounces when loaded – maybe smaller and lighter than the competition. It could be a good weapon for newcomers to start out with.

Best-Selling Guns of 2021 – SIG Sauer P365

The Sig Sauer P365 is another subcompact pistol that came in third place. Our review in 1945 said the gun is reliable and maybe even easier to conceal than the Glock 43. It fits many small holsters including waistband and pocket-size. The P365 carries more rounds (ten to fifteen-plus one) than the Glock 43. The magazines are double-stacked. It costs around $500 to $600.

Best-Selling Guns of 2021 – Springfield Armory Hellcat

With a good name for sales and marketing, the Hellcat comes up next as one of the highest-selling handguns.

If you are into subcompacts, you may want to give the Hellcat a try. It is a three-inch barreled pistol that is one-inch wide and weighs just 18.3 ounces unloaded. It comes with 11+1 rounds in the magazine, while the extended mag can hold 13+1 rounds. The grip texture is topnotch. External controls are designed for an easier to conceal pistol.

Best-Selling Guns of 2021 – Glock 17

Finishing fifth is the Glock 17. It’s popular with law enforcement and militaries around the world. A 1945 review said that the Glock 17 Gen 5 had an improved and comfortable grip. It’s accurate at 25-yards on the range with a 100-bullet sample shoot, according to the reviewer. A big selling point is its 17-round magazine. It has little recoil. The rail can hold various accessories such as optics and red dot sights. The price is around $600.

The trend in sales appears to be the popularity of subcompact pistols. The gun-buying public wants easy-to-carry handguns for self-defense. Gun carry laws are changing. For example, Texas has constitutional carry in which people who qualify under the law can carry a pistol in a public place in Texas without a license to carry. Some states also have forms of unrestricted carry. We’ll see if other states follow suit in 2022.

    “The Glock 19 is the easier to carry than the bother pistols in its class”
    Nonidea what that means because my S&W M&P is just as easy to carry as my Glock 19, is just as reliable but has a better trigger and ergonomics than the Glock.

    Who ever wrote this really doesn’t know much about guns. You can just tell by their writing. “The rail can hold optics and red dot sights”. I don’t think so, maybe lasers or lights.

    Glock pistols are neither single or double action. That would require an exposed hammer. The manufacturer refers to it as “safe action”. Do your research.

    This is a very poorly researched article,written by someone who obviously doesn’t have much experience with firearms. Some of the pictures and facts are completely off. Get some gun knowledge before you pretend you can write about them!
