Thanks to Synchronizor for this review
S&J Hardware (http://www.sjhardware.com) is a Canadian manufacturer & retailer of firearms accessories and other shooting-related products. They offer a number of add-ons and replacement components for shotguns, including a line of magazine extensions for the Remington 870 and others. A lot of S&J Hardware’s products have proven popular in the 870 community, such as their magazine followers and Velcro shell carriers, and I’ve personally used several of their accessories for years with good results. Their magazine extensions always sounded really good on paper, but I really hadn’t seen them in the wild much, and had no personal experience with them. This came up in a discussion on the Rem870.com forums, and soon afterward, Scott Mueller, S&J’s United States distributor (http://www.sjhardware.us), contacted me asking if I would be interested in having one sent over for evaluation. Obviously I was interested.
