There are compact 12 gauges, and then there's the Shock 'n' Saw. Mossberg took the 590 Shockwave, already a favorite for tight spaces, and bolted on an aluminum railed forend topped with the signature Chainsaw grip and retention strap. Wrap your support hand around that top handle and the gun points naturally from a low ready or hip position, with the strap keeping your hand planted through recoil and well clear of the muzzle. Out back, the Raptor bird's head grip does its job of steering recoil energy through your hand at an angle instead of straight into your wrist, which makes running full-power loads a lot more manageable than you'd expect from something this size.
Underneath the distinctive looks, this is the same pump action that has earned Mossberg its reputation over decades. You get dual extractors, twin action bars, positive steel-to-steel lockup, and an anti-jam elevator that keeps shells feeding smoothly whether you're cycling slow or running the tube dry in a hurry. The top-mounted tang safety falls right under your thumb and works the same for lefties and righties. The magazine tube features a clean-out cap, so maintenance doesn't require a full teardown, and the receiver is drilled and tapped if you want to add an optic or rail later.
The 14.375 inch heavy-walled barrel wears a stand-off breacher muzzle and a matte blued finish, with a simple brass bead up front that's fast to pick up at practical distances. The 3 inch chamber handles everything from light target loads to magnum buckshot, and the cylinder bore throws consistent, defensive-friendly patterns. The M-LOK forend gives you real estate for a light or other accessories, and the bottom rail adds even more mounting options, something most compact pump guns in this class can't offer.
At 5+1 capacity and roughly 26.37 inches overall, this is a firearm that tucks away easily but still brings 12 gauge authority when you need it. It's a blast on the range, a conversation starter in any safe, and a genuinely practical tool for truck, cabin, or home. Few pump guns manage to be this much fun and this useful at the same time.
It has a 3 inch chamber, so it runs standard 2.75 inch and 3 inch 12 gauge shells, from light birdshot to magnum buckshot and slugs. Keep in mind capacity is 5+1 with 2.75 inch shells and drops to 4+1 with 3 inch magnums. If you want reliable feeding with 1.75 inch mini shells, a drop-in adapter like the OpSol Mini-Clip is the popular fix on this platform.
Yes, the Chainsaw strapped grip mounts to the aluminum railed forend and can be removed if you prefer a cleaner setup. The forend itself features M-LOK slots plus a bottom rail, so you still have plenty of options for lights and accessories either way.
It gets your attention with full-power buckshot, but the Raptor bird's head grip is shaped to redirect recoil so it rolls through your hand instead of hammering your wrist. The Chainsaw top grip and strap give your support hand solid purchase, which helps a lot with muzzle control. Many owners start with reduced-recoil buckshot or mini shells for practice, and that's a smart way to build comfort with it.
The receiver comes drilled and tapped from the factory, so adding a rail or saddle mount is straightforward. Between that and the M-LOK forend with its bottom rail, you can set up a light, laser, or small red dot without much trouble.
