The inertia-driven action cycles reliably under adverse conditions and keeps follow-up shots fast without needing a gas system to maintain.

What Reviewers Say
Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.
I like to call it the ferrari of the tactical shotgun world.
The Beretta 1301 has been my favorite combat shotgun up until this point and the Benelli M4 gives it a run for its money.
I could outrun the shotgun meaning I could pull the trigger faster than the action could cycle leaving me with a dead trigger.
I love the ghost ring sighting system for Slugs and Buckshot for a combat style shotgun because you may be taking shots at a distance.
I can't outrun this shotgun and that is key because the Benelli M2 left me incredibly disappointed.
Customers Say
AI-generated insights derived from customer reviews and discussions on popular gun-enthusiast forums.
The Benelli M4 H2O Tactical gets consistent praise for reliability. Owners report it runs through varied ammunition without hiccups, including in wet or dirty conditions. The H2O corrosion-resistant finish is a practical feature for anyone storing or using the gun in a humid environment.
The semi-automatic action is well-regarded for enabling quick follow-up shots, and new shooters find the manual of arms straightforward. Experienced users appreciate the smooth cycling.
Customization comes up often in owner discussions. The Picatinny rail makes it easy to add lights, optics, or other accessories, and aftermarket stocks and slings are widely available.
Weight is the most common complaint. At 7.8 lbs the M4 is on the heavier side for a shotgun, and some find that tiring during extended range sessions or dynamic drills. The price is another recurring topic; the M4 costs more than many comparable semi-auto shotguns, though most owners consider the build quality to justify it.
