Tactical shotguns are undeniably useful, especially after customization with a flashlight, laser, red dot and six-shell side saddle. What do you consider when selecting shotgun accoutrements? Price would probably be the first consideration, followed by quality of the product, reputation of the manufacturer and also function. You may ask yourself, “Does this product meet my needs, at a price I am willing to pay?” However, something you may not have considered (but should) is weight.
Before you trick out your new inertia-driven shotgun, check the manufacturer’s recommendation regarding the maximum weight limit of the frame. This is because in an inertia-driven shotgun, the bolt free-floats between two springs. When the trigger is pulled, the shotgun fires and the frame recoils around the bolt. The bolt essentially stays still. If we add more than 500 grams of gear to the frame of our Benelli M2 or M3, for example, the frame may be too heavy to cycle the bolt—and it could induce malfunctions.
So, if you want to accessorize your inertia driven-shotgun with gear for defensive purposes or competition, remember to consider the products’ weight in addition to price, quality and function.
