Trijicon lists SA21 for a 9mm Sigma.

Professional gunsmith installation is HIGHLY recommended to avoid damage to the firearm and/or sights, and to preserve the warranty.

Free advice/voice of xperience: A professional gunsmith is rarely, if ever, a friend, friend-of-a friend, neighbor, co-worker or relative, especially a brother-in-law.
