My wife is interested in starting to shoot trap. And she currently has an 1100. I used to see guys shooting their 1100's, and they had some sort of clip attached to the receiver that kept the spend shell from being flung into your neighbor. If I remember right, the empty hung up on this clip, and did not eject from the receiver. Does anyone know what they are called, and or where you can get them? Any input would be greatly appreciated. Thanks
