Inside the Rock River Arms Polymer Single Stack 1911
I took two photographs of the RRA polymer 1911's guts at SHOT 2012. Here they are.
According to the spec sheet, the "polymer frame body" will allow "interchangeable colors." The weight is listed as 2.04lbs.
Note the screw on the forward portion of the trigger guard where it meets the dust cover
Polymer dust cover, trigger guard, and grip/magazine well, but the rails and guts are composed of a steel chassis. Doesn't appear to have a Swartz type firing pin safety.
