SIG Sauer P226

The SIG Sauer P226 and its variants are semi-automatic handguns chambered primarily in 9mm, .40 S&W and .357 SIG. The most notable of this model is the Tactical Operations variant used by Rika Minami as her personal sidearm. It differs from the standard P226 by its flared magwell and pistol grip. She customizes the handgun by adding bridge mount, a Docter MR01 reflex sight, and weapon light that is modelled after the Matrix Tactical M3 weapon light.

Plot
The P226 is never seen used by the group. However, the Secret Service uses it as their standard sidearm. One is seen used by an agent to kill the undead first lady and another is used by another agent to execute the chairman when he shows signs of zombification.
