Remington Model 95 with pearl grips and barrels open for reloading COP .357 Magnum derringer. The original Philadelphia Deringer was a small single-barrel, muzzleloading caplock pistol designed by Henry Deringer (1786–1868) and produced from 1852 to 1868, and was a popular concealed carry single-shot handgun of the era widely copycatted by competitors.

Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger, hammer/firing pin or frizzen, and therefore do not need a sizable receiver behind the barrel to accommodate a moving action, making them far less complex and more robust than revolvers or magazine/belt-fed firearms, but also ...
In larger caliber firearms, the shot start pressure is often determined by the force required to initially engrave the projectile driving band into the start of the barrel rifling; smoothbore guns, which do not have rifling, achieve shot start pressure by initially driving the projectile into a "forcing cone" that provides resistance as it ...
For example, while field hunting flushing birds, the first shot is usually closer than the second because the bird flies away from the shooter; so, the more open choke (and barrel) would be better for the first shot, and if a second shot is needed, as the bird is flying away, the more closed (and thus longer distance of an effective shot ...
Unlike single-shot firearms, which can only hold and fire a single round of ammunition, a repeating firearm can store multiple cartridges inside a magazine (as in pistols, rifles, or shotguns), a cylinder (as in revolvers), or a belt (as in machine guns), and uses a moving action to manipulate each cartridge into and out of the battery position ...
The multiple guns that comprise a Gatling being a much larger bulk of metal than other, single-barreled guns, they are thus much slower to rise in temperature for a given amount of heat, while at the same time they are also much better at shedding the excess, as the extra barrels provide a larger surface area from which to dissipate the ...

Higher efficiency can be achieved in longer barrel firearms because they have better volume ratio. However, the efficiency gain is less than corresponding to the volume ratio, because the expansion is not truly adiabatic and burnt gas becomes cold faster because of exchange of heat with the barrel. Large firearms (such as cannons) achieve ...
