Semi-Auto Firearms

Semi-automatic firearms fire one round per trigger pull and use the energy of each shot to cycle the action and chamber the next round. This category covers semi-auto pistols and rifles across calibers such as 9mm Luger, 45 ACP, 380 ACP, 22 LR and 5.56x45mm NATO. Compact carry pistols like the Sig Sauer P365 family sit alongside full-size duty-style pistols such as the Smith & Wesson M&P M2.0 and Springfield Armory Echelon, while semi-auto rifles like the Springfield Armory DB15 and Kel-Tec SUB-2000 cover a different set of uses.

Buyers typically compare caliber, magazine capacity, barrel length, frame size and optic footprint, along with included accessories like threaded barrels or factory red dot mounts. Listings here show current prices and stock from across retailers, so you can line up similar models side by side before you buy.
