How the Shockwave Is Classified
Mossberg describes the Shockwave as a firearm built with a bird's head grip and no shoulder stock. Federal law defines a shotgun as designed to be fired from the shoulder, and the ATF has made classification determinations on firearms like this. Rules change and are interpreted differently by agencies and states. Verify the current federal classification and your state's law before buying. We can point you to the ATF's published guidance, but we cannot give legal advice.
The Raptor Grip and How It Handles
The Raptor grip has a bird's head shape that helps with consistent hand placement and limits slipping under recoil. Without a stock, recoil goes through your arms and stance instead of your shoulder. Technique matters more than with a stocked shotgun. Many owners practice with light loads before using heavier defensive loads. Wear eye and ear protection and start slowly.
Capacity and Models We List
Our listings show Shockwave and 590S Shockwave models with capacities of 5 to 11 rounds depending on the model. Most are 12 gauge, and there are 20 gauge and .410 versions. Barrel lengths are around 14 inches on the Shockwave line. Overall length is short enough to store in places a full-length shotgun will not fit. Check each listing for the exact barrel length, chamber and capacity.
12 Gauge, 20 Gauge and .410 Options
The 12 gauge has the widest selection of loads and the most recoil. The 20 gauge kicks less, and the .410 is the smallest option with a smaller payload. Pick the gauge you can control, then match shells to it. See our 12 gauge ammo, 20 gauge ammo and .410 ammo pages.
State Law and Buying Rules
Some states restrict firearms by barrel length, overall length or pistol grip, regardless of federal classification. California, New York, New Jersey and Massachusetts are examples of states that have strict rules. Confirm your state's law before ordering. Ask a qualified attorney if you are unsure about your situation.
