The Steyr Arms claims (excerpts) as outlined in the lawsuit:

SIG SAUER has infringed and is continuing to infringe claim 1 of the `301 Patent by manufacturing, importing, distributing, marketing, offering for sale, and selling pistols having a plastic housing and multifunction metal part removably mounted therein (hereinafter “the Accused Products”). The Accused Products include, but are not limited to, the SIG SAUER P250 and P320 pistols.

The frame assembly includes a projection in the form of a locking tab which is received in a recess or mating slot inside the rear of the grip module (Exhibit C, p. 52). The trigger mechanism is located at least in part within the grip module and is supported on the frame assembly (Exhibit C, pp. 50, 52 and 63).

Lastly, the frame assembly includes control means in the form of a pin for locking the barrel in the barrel slide (Exhibit C, pp. 62 and 63).
