PPS m870 police wood real eject gas shotgun

Pump model with extremely real cartridge ejection, the gas is to be loaded in the cartridge. 
I have 4 cartridges, ideal for dry training. As I remember, there were some issues with two of them, but for dryfire drill/training they are perfect.
If you need more cartridges, I can send a pack of 5 for an additional cost.

The package also includes: 
recovery shell catcher
upper rail
