The heavy barrel, durable Parkerized finish, and 9-round capacity draw consistent praise from owners who want a shotgun built to last under hard use. Ergonomics are well-received. The ambidextrous safety, comfortable grip, and balanced weight distribution at 7.25 lbs are mentioned favorably. The ghost ring sights are cited as a practical improvement over standard bead sights for defensive work. Weight and 12-gauge recoil come up as the main considerations. Some users find the gun heavy for extended carry, and new shooters may need range time to get comfortable with full-power 12-gauge loads. Neither point is unusual for a tactical platform of this build. Overall the 590A1 consistently earns positive sentiment. Most owners consider it a reliable, well-built defensive shotgun that justifies the price point. ## Pricing **12 offers available** | Vendor | Price | |--------|-------| | Grabagun Com | $689.99 | | Gritrsports Com | $702.99 | | Shootingsurplus Com | $703.48 | | Kygunco Com | $712.94 | | Guns Com | $714.99 | | Sportsmansguide Com | $716.99 | | Palmettostatearmory Com | $720.99 | | Gunbuyer Com | $724.85 | | Impactguns Com | $728.19 | | Buds Gun Shop | $732.99 | *...and 2 more offers* ## Similar Products - [Mossberg 590A1 Tactical 12-Gauge Pump Shotgun - 20" Black Synthetic](https://gunsnation.com/p/mossberg-590a1-tactical-12-gauge-pump-shotgun-20-black-synthetic/UCHGBu4k) - [Mossberg 590A1 Tactical Pump Shotgun - 12 Ga, 18.5" Heavy Barrel](https://gunsnation.com/p/mossberg-590a1-tactical-pump-shotgun-12-ga-18-5-heavy-barrel/UCHGBrj3) - [Mossberg 590 Tactical Pump Action Shotgun, 12 GA 20" Barrel, 9-Shot](https://gunsnation.com/p/mossberg-590-tactical-pump-action-shotgun-12-ga-20-barrel-9-shot/UCHGBrXX) - [Mossberg 590A1 Retro Walnut 12 GA Tactical Pump Shotgun](https://gunsnation.com/p/mossberg-590a1-retro-walnut-12-ga-tactical-pump-shotgun/UCHGBu4F) - [Mossberg 590A1 Tactical Pump Shotgun, 12 GA, Magpul SGA Stock](https://gunsnation.com/p/mossberg-590a1-tactical-pump-shotgun-12-ga-magpul-sga-stock/UCHGBuLh) - [Mossberg 590A1 Tactical Pump Shotgun - 14" Barrel, Ghost Ring Sights](https://gunsnation.com/p/mossberg-590a1-tactical-pump-shotgun-14-barrel-ghost-ring-sights/UCHGBu83) --- *Data from [GunsNation](https://gunsnation.com)*
