There space six determinants that will recognize the maximum number of rounds any type of given firearm can hold. Occasionally maximum capacity can be boosted with aftermarket magazines. However, periodically the number of rounds a handgun can hold is minimal by the handgun design. If you room looking to purchase a handgun, the following characteristics will influence the maximum variety of rounds a handgun have the right to hold.Type the handgun (automatic, revolver, or Derringer/pocket pistol)Handgun dimension (full-size, compact, or subcompact)Caliber the the pistol (.38, 9mm, .45 ACP, etc.)Magazine layout (single ridge or double stack)Aftermarket magazinesMake and model of the pistol 
There are essentially three types of handguns. The first, and also one the the many common types of handgun, is the automatically reloading pistol. This form of pistol has actually a solitary chamber, and rounds space loaded instantly from a magazine together bullets room fired. The limiting variable on an automatically is the capacity of the magazine.
Next, top top our list of handguns, we have actually the revolver. Unlike automatic pistols, revolvers have actually multiple chambers, i m sorry each home a solitary round. These chambers exist in ~ the “wheel” of the revolver, and also the number of chambers is collection during manufacturing. As the create is pulled, or the hammer is cocked, the wheel rotates and aligns the next round in sequence with the shoot pin.
Finally, we have actually Derringer format pistols, i beg your pardon are occasionally referred to as pocket pistols. While not completely accurate, bag pistols have come to be synonymous with the true Derringer pistol. Comparable to revolvers, Derringers have a fixed number of chambers that each home a single round. However, over there is no wheel the rotates. Instead, rounds room fired in a details sequence if the pistol has much more than one chamber.
There are numerous variations of bag pistols. If the bag pistol is an automatic, or a revolver then the number of rounds is dictated by the overarching pistol type. However, if the pistol is not an automatic and has no “wheel” then it is minimal by the limit of a Derringer.


Generally, larger firearms are made to accommodate a bigger caliber round, much more ammunition, or both. While not always true, complete size firearms can hold an ext ammunition than their smaller sized counterparts.Given two guns that fire similar caliber bullets, made by the same manufacturer, with similar magazine construction (single ridge vs. Twin stack), the bigger firearm will be able to hold much more rounds. Every one of this suspect the firearm is an automatic and also not a revolver or bag pistol.
Full size firearms which space the largest deserve to hold the many ammunition. Compact models will have a slightly smaller magazine well, and also therefore hold fewer rounds. The smallest size is a subcompact handgun and also will have also less space for a magazine.
If handgun dimension can affect the variety of rounds the pistol have the right to hold, then ammunition size plays a comparable role. Pistols that fire a smaller round can potentially carry much more ammunition. However, the other components on our list also affect the number of rounds a pistol have the right to hold.
If there room two guns with all the same features except ammunition caliber, the handgun which provides a smaller caliber will have the ability to hold an ext ammunition. Due to the fact that the magazine setup is the same, a smaller sized round will certainly take increase less space and therefore allow an ext rounds to it is in loaded. Again, this go not apply to revolvers or bag pistols through a fixed number of chambers.

Automatic pistols are unique from the other varieties because they usage a magazine fairly than solved chambers. Therefore, this ar does not apply to revolvers and also Derringer layout pistols. With that said, magazines come in two different layouts, solitary stack and twin stack.
Single ridge magazines vertically align rounds into a column format. This type of newspaper is usually much more slender, i beg your pardon is great for covert carry. However, this format of newspaper is no the most reliable for increasing the number of rounds the handgun deserve to hold.
Double stack magazines likewise align the rounds vertically, yet the rounds space staggered essentially producing two columns rather of one. This an approach does do the magazine thicker, but allows more rounds to it is in loaded into a newspaper of comparable height.
Picture above is a single stack magazine from a 1911, a twin stack magazine from a Sig 9mm, and also a twin stack mag from a Glock .40 caliber pistol. The 1911 has a solitary stack newspaper that have the right to hold 8 rounds. Both the Glock and Sig have twin stack magazines that have the right to hold over 10 rounds.The Sig Sauer handgun deserve to hold 15 rounds, if the Glock .40 caliber handgun deserve to hold 13 rounds. Even though the magazine because that the Glock is native a complete size pistol the holds less rounds 보다 the magazine from the compact Sig. This demonstrates just how caliber, pistol size, and handgun version can influence the variety of rounds a handgun have the right to hold.

If increasing the number of rounds her handgun can hold is that importance, climate you’ll desire to make certain you obtain an automatic. Because of the nature of their setup, enhancing the number of rounds is a matter of developing a bigger magazine. Aftermarket magazines are plentiful, and also you can usually uncover larger magazines digital or in ~ your local gun show.Above is an extensive magazine because that the 1911 model. This magazine can hold 10 rounds (as opposed to the classic 8), however you’ll an alert that when the newspaper is put into the pistol that the newspaper extends beyond the boundaries of the magazine well.

Unfortunately, if you have actually a revolver, there is not lot you have the right to do to increase the variety of rounds her handgun have the right to hold. The same have the right to be said around Derringer layout pistols or any pistol v a fixed number of chambers. Over is a snapshot of an enlarge revolver, the resolved chambers carry out not permit you to quickly add much more rounds.
If every one of this no enough, the final determining aspect for how numerous rounds a pistol have the right to hold is the make and also model of the firearm. As an example we’ll look at two equivalent pistol models and examine how the variety of rounds in the magazine have the right to vary. An initial is the H&K P30 SK, and also a Sig Sauer P365. Both space chambered because that 9mm and also are subcompact models. However, the H&K provides 10 round, 13 round, and also 15 round magazines. Contrarily, the Sig only supplies 10 round and also 12 round magazines.
Automatic reloading handguns hold a number of rounds identical to the size and also setup the the magazine. Smaller single stack magazines will host a minimum of 6 rounds. Larger double stack magazines have the right to hold in overabundance of 19 rounds. Part manufacturers will provide a selection of magazines that have various capacities.Additionally, the aftermarket magazine sector offers and abundance of options for higher capacity magazines. For example, there are 100 round Glock north magazines the you have the right to likely discover at your neighborhood gun show. If these are not right for surprise carry, they are obtainable to pistol enthusiasts. Before purchasing, make sure these magazines room legal in your state.
The number of rounds the a revolver deserve to hold is figured out by the variety of chambers bored out that the wheel. A revolver can usually hold either 5 or 6 rounds. Revolvers that have actually 6 chambers are an ext commonly known as six-shooters. Ironically, those through 5 chambers space not well-known as five-shooters.Unlike your automatic counterparts, the amount of ammunition a revolver can hold is resolved by the variety of chambers, so there’s no aftermarket upgrades to boost the variety of rounds a revolver have the right to hold.
To date, the handguns that can hold the many rounds native the manufacturing facility are 9mm Glock models. The Glock 17 has several magazine configurations, the largest of i m sorry accommodates 33 rounds. of course, if we’re talking around aftermarket magazines then it will vary from pistol come pistol. Although, there are 100 ring drums easily accessible for Glock models (e.g. Glock 18) that deserve to be purchased at your regional gun show or online. Don’t suppose to find any gun manufacturers heralding this kind of magazine.
Now the we’ve talked around how countless rounds a total can hold, what about how plenty of rounds should her concealed bring hold? Your concealed lug pistol have to have in between 6-15 ring magazines. Plenty of subcompact and compact pistols have actually magazines the fit this range. While I tend to bring at the higher end, at some point it comes down to your capability to conceal her handgun.
One distinct advantage of an automatic is that you can hold additional rounds in a preventive magazine. I recommend delivering a preventive magazine in addition to your concealed pistol. Examine out the 5.11 Tactical concealed bring compression shirt which has actually a pocket for secondary magazine. Not only does this dual the lot of rounds you have access to, yet it additionally provides one more option have to you experience a failure with your major magazine.
To sum things up, the number of rounds a pistol can hold will certainly vary relying on a variety of factors. If she looking to carry much more rounds in her handgun, it’s best to get an automatic handgun, chambered because that a smaller round. Having actually an automatic enables you to acquisition aftermarket magazines which deserve to hold more rounds. Revolvers and also Derringer layout pistols have a set number of chambers, and also therefore a set variety of rounds that can be loaded.Regardless, that what option you walk with, make sure you can still conceal her handgun. Perform you have anything come add? recognize of any other pistols the hold an ext than 33 ring from the factory? leaving a comment because that our readers.
