The Ruger SR40 is perfectly sized to be comfortable and controllable with a slim, ergonomic grip and narrow slide. Featuring a short reach from the backstrap to the trigger, the SR40 creates a comfort level that will challenge any standard-size, striker-fired pistol available today. The structurally rigid, recoil-reducing, glass-filled nylon frame and stainless steel slide combine to create a low-maintenance, rugged and reliable handgun.

The Ruger SR40's custom slide design reduces recoil and slide velocity, making it more comfortable to shoot than many of its competitors.
