Air pistols fire .177 BBs or pellets using CO2 or pump power, making them inexpensive trainers that mirror the feel of a carry gun. CO2 semi-autos from Umarex and Sig Sauer replicate popular pistol designs, while Crosman variable-pump classics reward marksmanship fundamentals. Velocities run from around 400 to 480 fps. Shop Crosman, Daisy, Umarex, Sig Sauer, and Gamo for backyard targets, pest control, and low-cost practice.
