FAQs

Comparison FAQs

Is the Benelli M4 worth the price?

For serious defensive use, yes — the M4’s semi-automatic operation eliminates the manual pump under stress, reduces felt recoil, and cycles at 120+ rounds per minute. The USMC didn’t adopt it for its price.

Why is the Mossberg 590A1 considered military grade?

The 590A1 is the only pump shotgun to pass the US military’s MIL-SPEC 3443 endurance testing — 3,000 rounds of 00 buck with no parts breakage. The aluminum trigger guard, heavy-walled barrel, and bayonet lug are the tells.
