Format: PDF (765 KB) GET

As a long-time outdoor enthusiast and firearms advocate, I’ve spent years evaluating and customizing shotguns for various purposes – from home defense to 3-gun competitions. The Mossberg 590A1 consistently stands out as a reliable, versatile, and affordable platform. This guide will delve into everything you need to know about the 590A1, its siblings like the 500 and Shockwave, potential upgrades, and what to consider when choosing the right model for your needs. We’ll cover everything from basic Mossberg 590A1 upgrades to understanding the nuances between the Mossberg 590 vs 500.

Understanding the Mossberg Lineup: 500, 590, and Shockwave

Before diving into upgrades, let's clarify the differences between the core Mossberg models. The Mossberg 500 is the original, known for its affordability and wide availability. However, the Mossberg 590 series, and specifically the Mossberg 590A1, offers improvements in durability and functionality. The key difference lies in the receiver: the 590 series features a heavier-duty receiver designed for heavier loads and more frequent use. This makes the 590 a favorite among law enforcement and military personnel. (Mossberg Official Website)

The Mossberg Shockwave is a unique variant, featuring a bird's head grip and a short barrel (typically 18.5 inches). While compact and maneuverable, it requires practice to master due to its recoil and unconventional grip. The Mossberg Shockwave cost generally falls between $400-$600, depending on features. Some users report Mossberg Shockwave problems related to recoil management, especially for new shooters.

Mossberg 590A1 vs. 590S: What's the Difference?

The Mossberg 590A1 and Mossberg 590S are often confused. The A1 model includes a heavier barrel, a bead sight, and a synthetic stock. The 590S, on the other hand, typically features a shorter barrel (often 20 inches) and may have different stock options. The Mossberg 590s price generally ranges from $450 to $650, while the Mossberg 590A1 price is usually slightly higher, around $500-$700. Both are excellent choices, but the A1 is often preferred for tactical applications due to its heavier barrel and more robust construction.
