The limiting factor on an automatic is the capacity of the magazine. Next, on our list of handguns, we have the revolver. Unlike automatic pistols, revolvers have multiple chambers, which each house a single round.
As the trigger is pulled, or the hammer is cocked, the wheel rotates and aligns the next round in succession with the firing pin.
Finally, we have Derringer style pistols, which are sometimes referred to as pocket pistols. While not completely accurate, pocket pistols have become synonymous with the true Derringer pistol.
Similar to revolvers, Derringers have a fixed number of chambers that each house a single round. However, there is no wheel that rotates. Instead, rounds are fired in a specific sequence if the pistol has more than one chamber.
There are several variations of pocket pistols. If the pocket pistol is an automatic, or a revolver then the number of rounds is dictated by the overarching pistol type. Generally, larger firearms are made to accommodate a larger caliber round, more ammunition, or both. While not always true, full size firearms can hold more ammunition than their smaller counterparts. Given two firearms that fire identical caliber bullets, made by the same manufacturer, with similar magazine configurations single stack vs.
All of this assumes the firearm is an automatic and not a revolver or pocket pistol. Full size firearms which are the largest can hold the most ammunition.
Compact models will have a slightly smaller magazine well, and therefore hold fewer rounds. The smallest size is a subcompact handgun and will have even less space for a magazine. If handgun size can affect the number of rounds the pistol can hold, then ammunition size plays a similar role.
Pistols that fire a smaller round can potentially carry more ammunition. However, the other factors on our list also impact the number of rounds a pistol can hold. If there are two firearms with all the same characteristics except ammunition caliber, the handgun which uses a smaller caliber will be able to hold more ammunition. Because the magazine setup is the same, a smaller round will take up less space and therefore allow more rounds to be loaded.
Again, this does not apply to revolvers or pocket pistols with a fixed number of chambers. Automatic pistols are unique from the other types because they use a magazine rather than fixed chambers. Therefore, this section does not apply to revolvers and Derringer style pistols. With that said, magazines come in two different layouts, single stack and double stack. Single stack magazines vertically align rounds into a column format. This type of magazine is usually more slender, which is great for concealed carry.
However, this style of magazine is not the most efficient for increasing the number of rounds the handgun can hold. Double stack magazines also align the rounds vertically, but the rounds are staggered essentially creating two columns instead of one. This method does make the magazine thicker, but allows more rounds to be loaded into a magazine of similar height. Picture above is a single stack magazine from a , a double stack magazine from a Sig 9mm, and a double stack mag from a Glock.
The has a single stack magazine that can hold 8 rounds. Both the Glock and Sig have double stack magazines that can hold over 10 rounds. After pulling the trigger the hammer hits a transfer block, which hits the firing pin, causing the gun to shoot. This means that lowered hammer is not resting on the cartridge and no bump will cause the gun to fire. Get to know it better and find out if it has a transfer block or maybe even a hammer block a mechanism that blocks the hammer from falling accidentally.
But now you know why cowboys only loaded 5 rounds in their revolvers. By the way, there is a legend that cowboys had a rolled up bill in the sixth chamber to pay the undertaker in case they die. This is, of course, a myth, because refusing to use your sixth slot at a shootout would be stupid. Also, that bill would burn pretty quickly from all the hot gasses escaping the cylinder.

The trigger lever pushes the hammer backward. As it moves backward, the hammer compresses a metal spring in the gun stock the handle.
The diagram above shows a coiled spring; uncoiled tension springs are also used in revolvers. At the same time, a pawl attached to the trigger pushes on a ratchet to rotate the cylinder. This positions the next breech chamber in front of the gun barrel. Another pawl lodges in a small depression on the cylinder. This stops the cylinder in a particular position so it is perfectly lined up with the barrel. When the trigger lever is pushed all the way back, it releases the hammer.
The compressed spring drives the hammer forward. The firing pin on the hammer extends through the body of the gun and hits the primer. The primer explodes, igniting the propellant.
