The Shadow Systems CR920 magazine basepad extension, +3 rounds (Shadow Systems part no. SG9S0056EXT) turns a standard 10-round CR920 magazine into a 13-round magazine. Shadow Systems supplies it as a complete drop-in assembly with the front section, the rear sections and a locking pin. The CR920 was designed with an extra powerful magazine spring from the start, so the factory spring stays in place for the conversion.

Key Specifications

• It is compatible only with standard 10-round CR920 magazines, not the CR920X or CR920XP magazines.
