Bersa Thunder Combat: The Thunder is a traditional double-action/single-action (DA/SA) semi-automatic pistol that has proven its reliability over the years. The Thunder Combat is enhanced for concealed carry with a lower-profile slide, a rounded triggerguard and a small beavertail. The large slide serrations make racking the slide simple and the ergonomic rubber grips with finger grooves make controlling this .380 ACP easy.
