Get extra mags, fill them up & shoot more without having to stop for more ammo. Great way to extend shootin' fun with your Crosman C21 or C31 CO2 BB pistol.

Things I liked: Great interchangeability.
Things I would have changed: It does not work in the Crosman c11. It looks the same but no. And Swiss Arms has one that looks the same, but don't try it - it will get stuck!
What others should know: Know which guns it does work in and use a paint pen to ID the side of it.
