This is the Ruger EC9S, a “New & Improved” version of
the highly-successful LC9S pistol. The EC9S is a striker-fired
semi-auto designed for the concealed carry market. It uses the same
magazines as the LC9S, with the biggest obvious difference between
the two beings the fact that the sights on the EC9S are machined
directly into the slide. The EC9S has a slim, lightweight and
compact design, with glare-reducing rear facing cocking serrations
and a finger grip extension floorplate that can be added to the
7-round magazine for comfort and improved grip. Safety features
include integrated trigger safety, manual safety, magazine disconnect
and an inspection port that allows for visual confirmation of a
loaded or empty chamber.
