Franchi Affinity is the rebirth of the Franchi line of inertia-driven semi-automatic shotguns. The Affinity is known for its slender stock and light-weight. It is everything a mountain gun should be with enough fire-power to take down a newly flushed out covey and sturdy enough to endure the outdoor elements. Customers usually inquire about the difference between Franci’s Inertia-driven system verses Benelli’s Inertia-driven system. The answer is: Not very much. The Benelli’s recoil spring is in the buttstock, while the Franchi’s recoil spring resides around the magazine tube. Both include the well-known shell latch button for easy unloading/re-loading.
