By The Numbers - Smith & Wesson M&P12

It's a shotgun. The interchangeable choke tubes help with overall patterning though.
It’s a pump shotgun, and it’s tough to mess up. The gun cycles exceptionally well and does so with gusto. I couldn’t get it to malfunction and had to set one up to get test fixing malfunctions.
It’s a new gun on the market, so customization is scant. We can toss on optics and lights, and that’s about it.
Ergonomically a lot of the gun is well made and well thought out — a lot of the controls are ambidextrous and very easy to reach and use. The two significant downsides come from the length of pull and how tough it is to reload.

KelTec KS7


The KelTec KS7 utilizes a bullpup configuration to give users an 18.5-inch barrel while keeping an astonishingly short 26.1-inch overall length. Capacity remains a solid 7+1 despite how short this shotgun is, and at 5.9 pounds, it feels as light as it looks. The KS7 is a great option for home defense or any other roles that may require a compact, but controllable shotgun.

final verdict

“The S&W M&P 12 gauge is a powerhouse of a shotgun. It brings the bullpup shotgun from a fantastic concept to a professional-grade firearm — cycling, firing, ejecting, and performs admirably. Plus, you get an SBS-sized package without the pesky stamps and low capacity of an SBS. What’s not to love?” – Sean Curtis
