Best shotgun for self-defense at home

Gunprime was great in having the 20 guage shockwave at a reasonable price and getting it to me in a timely fashion. I love this shotgun and it will replace my Remington Model 1100 for self defense at home. Lightweight,short and fun to shoot. Less recoil for the wife in the 20 guage. I am recommending this shotgun to all my friends and relatives for home defense.

Exactly what I was looking for

This Mossberg shotgun also comes in a 20 ga for us smaller ladies. Comfortable grip, lightweight and packs a punch!

Great buy!

Been looking for this one for a while and found it at GunPrime for a great price! Purchased, transferred and picked up within 2 weeks! Status notifications at every step so I knew where my order was during the entire process. I would definitely order again from GunPrime and will recommend this site to friends and family.

Was very hesitate to make a purchase across the country, but couldn’t have been happier.

Within 3 hours of purchase UPS had this package and it was on its way. Purchased for home defense, thankfully have not had to use it, and hopefully never will. I like the compactness of this weapon, especially for home defense. I am very pleased with this gun, and would definitely buy again. Have recommended it to friends.

Gunprime ROCKS!

I'd been searching for over a year for a Mossberg 590 Shockwave in 20 ga when a friend told me about I checked it out and Boom! there it was. I bought mine for a great price and they shipped it to my FFL in record time. I can't describe how happy I am with the service I received from Gumprime. They're going to be my go-to site in the future. My wife and daughter are super impressed with this model Mossberg in 20 ga. I'll probably have to buy another for them.

Simply AWESOME, Read on.......

First off, the "service" I received from GunPrime is second to none. From the selection, to the purchase, to the shipping to a local FFL, the tracking, the notification everything was PERFECT, effortless with zero worries. Even the after sales follow-up was first class.
The 590 Shockwave in 20 gauge is the perfect home defense weapon. It's light enough for my 95 pound wife to handle.It's 26.5 inches long... so you can get around inside the house with it.It does not take long to get used to the "grip" of the 590 Shockwave.Add a Picatinny top rail and a laser pointer and you are ready to neutralize any threat to your family or home.The release lever is easy to work, the safety being in the middle can be released with either hand and SHOWS if it's on or off.The feeding is flawless, no mistakes, no disappointments. Thanks Gunprime, you have a lifelong customer. FYI I was NOT paid for this Product Review.

Exactly what I wanted and expected

This has been on my wish list for a very long time and super glad I finally "pulled the trigger"! The 20 ga has all the functionality and knockdown power I want but with a lot less recoil. I bought this predominantly as a home defense weapon and it's fun as hell out on the range also. Shoulda bought it years ago . . . I do wish the 20 gauge offered more configuration options and accessories, but I knew that before I made the purchase. In addition, Gunprime made the purchase very easy and the price was right

5 *s for gunprime's painless communication and s/h. Ordered 1/5, to my FFL on 1/12! Filled out the 4473 1/15 & took it straight out to the desert! Didn't clean it - out of the box & on the firing line. Fed it everything from 7.5 to #1 (my HD Rio RB209) to 3/4 oz slugs - every load cycled with 0 issues. IMHO #1 buck in a 20ga is an outstanding combo for HD (especially for my wife) - but - what REALLY makes the package lethal is the addition of a rail and a Laserlyte CM-MK4. This center mass laser turns it into a point-n-shoot from ANY position CQB/HD no-brainer DRT weapon!!! Very highly recommended!!!
