I’ve shot a gun or two, so I know from experience that your handgun’s frame size can make an enormous difference in how accurately you can shoot and how comfortable it is to carry. We will look at the main handgun frame sizes and their differences.
Different companies seem to have their own set of rules for what category they will stick their guns in. No set industry standard makes it difficult to list measurements, so the following information isn’t set in stone. The one common denominator is the barrel length, not the overall length or height. Hopefully, the following information will help you narrow down your search.
One important rule is that the smaller the gun is, the harder it will be to control, and because of that, accuracy will begin to drop fast with most shooters. Because of that, manufacturers frequently pair a smaller frame gun with a smaller caliber round. Magazine capacity plays a part in how big the gun will be, and magazines come in double-stack and single-stack designs. If you cannot control your firearm and get shots on target when you need to, the round count will not matter.
In this article, I’ll cover four different frame sizes of handguns and list the pros and cons of each. The more you know about these frame sizes, the better you’ll be able to choose the best gun for your needs, whether you’re a beginner or a pro.
Usually, full-size frames are the biggest and heaviest. They are great for shooting targets and protecting your home because they are accurate and easy to use. Because these bigger guns have more weight, they are easier to control and shoot more accurately. Full-size frames usually have a longer barrel and a bigger magazine so that you can shoot more shots without reloading. But because of their size, they may not be the best for concealed carry because they may be too big to hide easily. The larger size can also be hard for people with smaller hands, causing discomfort and making it harder to hit the target.
A full-size barrel is usually over 4.5 inches long and has a typical overall length of 7.5 inches. They are usually available in 9mm, .40 S&W, and.45 ACP. They occasionally come in.357 SIG, and more frequently, are becoming available in 10 mm.
Depending on the caliber of the gun, the magazine can hold anywhere from 13 to 20 rounds. Some of the more common guns that fall into this category are a Glock 17, Glock 21, Beretta 92F, SIG Sauer P226 or SIG P320 XFULL, and a Smith & Wesson M&P 2.0 full-size series.
Compact frames are an excellent compromise between full-size and subcompact frames. Since we can use them in more ways than full-size frames, we often use them for concealed carry and home defense. Compact frames are a good choice because they are easy to carry and not too big. They are large enough for a good grip and have manageable recoil, but they are still small enough to hide. You can also use them for target shooting, making them a popular choice for people who want a gun that can do it all.
A compact frame barrel is in the 3.5-inch to 4.5-inch range. The predominant calibers are the same as a full-size, but the magazines have less capacity. A compact frame magazine has a capacity in the ten- to fifteen-round range. The Glock 19, Glock 23, SIG Sauer P229, SIG Sauer P320, and Smith & Wesson M&P 2.0 Compact are all in the compact frame category.
In part two of a handgun’s frame size, we will review subcompact frames and “pocket pistols.”
