It is most well known for its \"2011\" modular frame guns (so-called because the lower grip and trigger guard, which is made of a fiber reinforced plastic, is a separate component from the metal upper portion of the frame that comprises the dust cover and frame rails). STI and Strayer Voigt Inc. share the patent on the modular frame."@en . .
