The Stoeger Cougar is a semi-automatic large-frame pistol chambered in 9mm, .40 S&W and .45 ACP. Features include a rotating-locking system, which means the barrel stays straight and actually spirals as the slide pulls back. On other systems the barrel just sort of sits and, as the slide pulls back, dips down in turn lifts the front. The Cougar has an ambidextrous safety that works as a de-cocking lever, so shooters can change between double and single-action. Its Bruniton finish doesn’t glare, is corrosion resistant and comes in black, silver, and silver and black. Its ergonomically friendly grip is a very popular feature. Most ergo-grips have finger grooves, but the Cougar’s is bigger and round.
