The Mossberg 590 Shockwave is a 14-gauge pump-action shotgun built on the legendary 590 platform, now in a compact 20" barrel configuration that delivers serious firepower in a maneuverable package. Model 50657 brings the reliability Mossberg shooters have trusted for decades to a 6-round capacity, making it a practical choice for home defense, tactical training, or situations where you need a shotgun that doesn't sacrifice handling for power. The 14-gauge brings more shot energy than a standard 12-gauge while staying in a footprint that works in tighter spaces.
This pump-action design puts you in complete control—there's no relying on semi-auto reliability or dealing with recoil management systems. You work the action, you make the shot. The 590 platform has proven itself in law enforcement and military use, and that same durability carries over here. The 20" barrel strikes a balance between sight radius and portability, useful whether you're running drills at the range or setting up for home defense scenarios.
The 6-round magazine gives you enough on-hand capacity for most situations while keeping the overall gun slim and manageable. If you're drawn to pump shotguns for their simplicity, redundancy, and raw reliability—and you want the extra punch a 14-gauge offers—the 590 Shockwave deserves a hard look.
| Gauge | 14-Gauge |
| Action Type | Pump-Action |
| Barrel Length | 20" |
| Magazine Capacity | 6 Rounds |
| Model | 50657 |
A 14-gauge shotgun fires a larger pellet payload than 12-gauge, delivering more shot energy downrange. It's less common than 12-gauge, so ammunition availability may vary by region—confirm local supply before purchase.
The pump-action design, reliable platform, and compact 20" barrel make it suitable for home defense applications. Always verify local laws regarding shotgun barrel length and magazine capacity in your jurisdiction.
Pump-action (also called slide-action) means you manually cycle the fore-end to eject a spent shell and chamber the next round. It gives you complete control over each shot and doesn't rely on semi-automatic gas or recoil systems.
