Weighing just 9.4 oz (266.5 g) this is Ruger's first entry into the field of tiny, ultra-light defensive pistols. LCP stands for "Lightweight Compact Pistol" and was designed in direct response to customer requests for a compact firearm for use by police as a back-up, and as a defensive handgun for civilian concealed carry needs.
The pistol has a glass-filled nylon frame, a two-finger grip, and a through-hardened blued steel slide. It is similar in appearance to the Kel-Tec P-3AT which weighs 8.3 oz. and uses a similar tension spring for the lightweight hammer, identical locked breech mechanism, and similar takedown method. The main differences are the Glock style extractor and the incorporation of an external slide stop. It is possible to tell if there is a round chambered by looking at the "view hole" next to the extractor.
In 2013, a seven-round extended magazine was released for the LCP.
