FAQ
What makes the Mossberg 590A1 different from the standard 590?
The 590A1 has a heavier 9mm barrel wall (vs. 7mm on the 590), an all-metal trigger guard and safety (no polymer), and is the model that passed US military MIL-SPEC 3443E testing. It is the heaviest and most durable version of the Mossberg 500-series pump.
What magazine extensions fit the Mossberg 590A1?
The 590A1 uses the same magazine tube thread as the 500/590 platform. Most 500/590 extensions fit the 590A1. However, the 590A1 is commonly used in configurations with specific magazine capacities — the 9-shot model has a longer tube that affects which extensions will work. Confirm your model's tube configuration before ordering.
Does the Mossberg 590A1 come with a bayonet lug?
Some 590A1 configurations include a bayonet lug — specifically the models with a 20-inch or longer barrel. It is a feature from the military specification. Whether you need it is a personal choice, but it is one of the 590A1's distinctive features.
Is the 590A1 worth the price over the standard 590?
For most users, the standard 590 is more than adequate. The 590A1's advantages — heavier barrel, all-metal controls, MIL-SPEC testing — matter most under sustained high-volume fire or in a professional duty context. For home defense and occasional range use, the 590 performs the same job for less money.
