Based off the iconic Mossberg 500 platform, the Mossberg 500 Chainsaw is a pistol-grip pump-action shotgun without a stock that features a wrap-around chainsaw-style hand grip incorporated into the forend. With the support hand above the barrel, counter force levels the muzzle as it kicks simultaneously cycling the action. It takes some time getting the hang of firing the Mossberg 500 Chainsaw as you’re essentially just firing from the hip and you’ll probably miss the first few times. However the chainsaw-style grip does a really good job at keeping muzzle flip under control.


When the pump handle is held on the side, the shotgun can be held to eye level and can serve as an off forward grip. Shooting like this is pretty difficult however.



In addition to the chainsaw-style grip, there are three Picatinny rails on the forend for mounting accessories such as lights or lasers. The 500 Chainsaw has a stand-off barrel that is intended for breaching doors, the rigid teeth on the muzzle also gives this shotgun a very aggressive look.



The Loading and operating the 500 Chainsaw is the same as any Mossberg 500 or 590, even the position of the safety selector (above the pistol grip) is the same as other Mossberg models. Pushing the selector into the forward position will expose a red dot indicating the shotgun is ready to be fired.



What really makes this 500 unique to other pistol grip shotguns is that it has a “chainsaw” handle attached to the pump as an aid for “accuracy” when shooting from the hip, however this is a conundrum because after about ten feet nothing is accurate when shooting from the hip. Sure it was fun, but very impractical.

Final Thoughts
I would recommend the Mossberg 500 Chainsaw strictly for personal defense (although not the best shotgun for that task) and Law Enforcement SWAT entry teams; moreover, this configuration is impractical for use with trap shooting, hunting, and even target shooting. Overall the Mossberg 500 Chainsaw pump shotgun is a very aggressive and intimidating looking platform with better usage in zombie video games and Hollywood movies than in real life applications.
