A few years ago, gun manufacturers responded to consumer demand for more firepower out of their concealed-carry handguns. SIG Sauer answered with the SIG P290. Later, it offered a model with some improved features, the SIG P290RS, which designates a restrike capability. The pistol has a full double-action design so that each squeeze of the trigger will cock and release the hammer for a full strike on the firing pin. This allows for an easy double-strike capability in case of a light primer hit or a hard primer.
Other added features include an extended beavertail frame, minimizing the risk of hammer bite or slide interference, a reconfigured slide stop/release, a smaller and redesigned magazine release and a finger extension magazine base for a firmer hold.
