The Mossberg 590 passed the US military's MIL-SPEC 3443E testing — a standard that requires the shotgun to fire 3,000 rounds with minimal failures. It features a metal trigger guard and safety, heavy-wall barrel, and a more robust construction throughout compared to the 500.
We carry Mossberg 590 parts built to the same standard as the gun. Extensions, springs, and hardware that fit correctly and hold up under real use.
FAQ
What is the difference between the Mossberg 590 and 590A1?
The 590A1 is the enhanced version — it adds a heavier barrel (9mm wall vs. 7mm on the 590), a metal trigger guard, and is the model that passed military MIL-SPEC testing. The 590 is the civilian version with a slightly lighter build. Both are excellent guns; the 590A1 is overkill for most users but is the hardest-use option.
Are Mossberg 500 and 590 accessories interchangeable?
Most are. The 500 and 590 share the same basic receiver and magazine tube design. Magazine extensions, stocks, shell carriers, and most accessories are cross-compatible. Some barrel-specific accessories differ. Always verify fitment, but in most cases 500 accessories will work on a 590 and vice versa.
What magazine extensions fit the Mossberg 590?
The 590 uses the same magazine tube thread as the Mossberg 500. Extensions designed for the 500/590 platform will fit the 590. We carry extensions adding 2 to 4 rounds. Always replace the spring when extending the tube, and confirm barrel length does not interfere with the extension.
Is the Mossberg 590 good for home defense?
Yes — the 590 is one of the most proven home defense shotguns available. Its heavy construction, reliable action, and large aftermarket make it a top choice. The most practical upgrades for defense use are a magazine extension, shell carrier for faster reloads, and a sling.
