#590M

Mossberg has just signaled the commercial availability of their latest Shockwave firearm chambered in 12 gauge scattergun bliss. The Shockwave  590M was announced earlier this year leading up to the SHOT Show in Vegas, sporting magazines over the more traditional tube-fed Shockwave. In case you’ve been living in a cave, had a While You Were Sleeping event, drafted into the Space Force and immediately deployed to the outlying terraformed planets or otherwise refuse to live in the modern world, the Shockwave is not a Shotgun nor is it an NFA controlled weapon. Although chambered In a gauge and not a caliber and having a barrel shorter than 18”, the combination of overall length and having no shoulder stock leaves the 590M categorized strictly as a firearm. Cash and carry… in most places.

How many times can the 100+ year old pump action shotgun design be refined to keep shooters interested? Who knows, but it is pretty clear that we have yet to see any signs of hitting a wall. On its surface, the Mossberg 590M simply looks like a modified tube fed shotgun that accepts magazines, much like other scattergun platforms have done for decades.

At first glance, Mossberg’s new 590M magazine-fed shotgun is a progression of their popular and reliable scatterguns. Look a little closer, however, and you will see some potentially industry-changing technology: the new magazines come in double-stack form. In capacities ranging from five to 20 rounds, the thick form factor allows for high shell capacities without the excessive length found in other mag-fed shotgun platforms.
