SIG Sauer system

<p>The SIG Sauer system is a type of <a href="/facts/Action_(firearms)/R2APeqab">action</a> found in self-loading handguns. It is a refinement of designs based on the work of both <a href="/facts/John_Browning/8WCE1X2d">John M. Browning</a> and <a href="/facts/Charles_Petter/gnnQToGr">Charles Petter</a> which began with the <a href="/facts/Colt_M1900/c84qQwq3">Colt Model 1900</a>, progressed to the <a href="/facts/Pistolet_automatique_mod%C3%A8le_1935A/0HnMf7Nq">French Model 1935A</a>, and later the <a href="/facts/SIG_P210/BwR6sxq3">SIG P210</a> handgun. This action first appeared in the United States on the <a href="/facts/Browning_Hi-Power_BDA/cKyFBT5L">Browning BDA</a> (Browning Double Action) <a href="/facts/.45_ACP/hEdjsBlQ">.45 ACP</a> caliber handgun around 1975. It represents a design which optimizes the cost of production of handguns while instilling high levels of accuracy and dependability. It is the basis for several <a href="/facts/SIG_Sauer/fEKX4BW9">SIG Sauer, Inc.</a> designs which have been widely adopted for police, military, and civilian use and is the action used in the <a href="/facts/SIG_Sauer_M17/RN0yxINx">M17 and M18</a> sidearms of the United States Armed Forces. It has become a highly copied design found in many parts of the world today.
