Compact, Manageable Recoil: Mossberg 590 Shockwave 20 Gauge!
Big boom in a small package, but easier to manage. We have the Mossberg 590 Shockwave in 20 Gauge, the ultimate compact pump-action for camp defence or convenient storage.
This isn't a sawed-off; it’s a factory-produced, Non-Restricted firearm designed to meet Canadian length requirements while remaining incredibly short and handy. The 20-gauge chambering offers similar stopping power to a 12-gauge but with significantly less recoil, making it faster to shoot and easier to control.
Key Features & Specs:
