Shadow Systems SG9S-00-56-P1 CR Magazine +1 Extension

This magazine extension adds one additional round to the CR920 magazine. Add this to your stock 10-round magazine to take the capacity to 11 rounds.

The basepad is contoured to create a rest for your pinky. In addition to getting an extra round, you will get more control over the pistol.

The +1 basepad is slightly bulkier than the pinky extension. If you are looking for more control, but do not want to add any bulk to the grip, go with the pinky extension.

The assembly goes directly on to your existing 10-round tube and does not reuse any components from other basepads (all the parts you need are included in the assembly).

If you need a replacement locking pin for this basepad, it is the same as the MR/DR/XR Trigger Housing Pin.
