desertcart.com : Monstrum Side Saddle 12 Gauge Shotgun Shell Holder | Compatible with Maverick 88/Mossberg 500/590/Shockwave Series Shotguns : Sports & Outdoors

Review: Great product, great company, great customer service - Ordered this item for, my recent purchase of my Mossberg Maverick 88. Bought this as the combo package with the two barrels, and wanted to stay at a budget point. With that said, I wanted to accessorize it, but not spend a ton of money. I bought the Monstrum side saddle, and didn't have any preconceived notions as to how good it was. When it arrived, I was pleasantly surprised at how solid it was and how nicely built. I honestly just expected a piece of plastic. It has a great metal backing plate. It was also designed perfectly, and lined up exactly with the holes for installation. Easy to read and understand instructions made installation a breeze. After a day at the range, it worked perfectly. Upon cleaning the firearm post shooting, I did realize it was a little loose. That did not surprise me, as the force of 100 rounds through a 12 ga shotgun would knock anything loose. I also never used any loctite on installation. ( hindsight) When I tried to tighten it up, I think I added a little too much force, and probably stripped one of the mounting screws....my fault, not the product. I reached out to Monstrum, to buy replacement screw/pin, so I could remedy this issue. The gentleman asked for a copy of my order ( gave the desertcart screenshot picture) and my address. He never asked for any kind of payment at all. Two days later the parts showed up, and perfect delivery. Outstanding customer service and standing behind their products. I wish all companies were this good. Highly recommend their products.
