Nothing can test a firearm like Military and Law Enforcement use which is why the Mossberg 590A1 Tactical 12 Gauge Pump Action Shotgun is still in use by many agencies. With it’s heavy walled barrel it is able to withstand years of heavy use while still remaining reliable. It has dual extractors that help to extract empty shells from the 3-inch chamber without getting stuck and reliably eject them from the gun so you can insert another shotshell. This Shotgun also features twin action bars on the pump action to provide a smooth operation that won’t bind when loading a new shell into the chamber. The anti-jam elevator helps when lifting new rounds from the magazine tube up into the chamber. All of these features make for a faster rate of fire with reduced risk of creating a malfunction. With decades of service use on its back, the 590A1 is a perfect choice for home defense and personal protection.
