What a great addition to home defense! Practically doubling the number of shells means plenty of firepower at the ready if racking the slide fails to dissuade a determined intruder. Softer shooting Aguila slugs and buckshot means even smaller frame defenders can control the ol’ family 12 gauge. The OPSol mini-clip is a perfect match for my Mossberg 500 with the 18.5” security barrel and pistol grip. I am impressed with the quality of the product. The ease of placing it in and removing it from the shotgun lets me switch from 2 1/2” and 3” shells to mini-shells and back in a matter of seconds. Finally, it is good to find a company that offers a solid product at a very fair price and then follows it up with proper customer service. I’m very satisfied with my mini-clips (I bought three!) and I confidently recommend OPSol of Texas as a reliable provider of a quality firearm product.
