An air pistol is a handgun-sized airgun that fires a small projectile with compressed gas or air instead of gunpowder. Every pistol in this collection shoots .177 caliber (4.5mm) steel BBs, and the two revolver families can also fire .177 pellets with the right cartridges. They are made for plinking, backyard target practice and getting a feel for a classic handgun design.
Start with the power source. Most models run on a single 12-gram CO2 cartridge, which gives you repeat shots and realistic action. You can browse those in CO2 air pistols. If you would rather skip CO2 completely, a spring pistol is cocked by hand before each shot.
Then pick the style you like. Choose a semi-auto like the 45 or 380, a select-fire 009, a double action 357 revolver, or a single action Old West revolver such as the Schofield or 1858 from the Barra Cowboy Series. The answers below cover speed, ammo and which pistol suits a first-time shooter.
