The Franchi Affinity 3 delivers Benelli's Inertia Driven operating system at a price that makes it the smart-money waterfowl autoloader. This 20 gauge configuration wears Mossy Oak Bottomland over a 26" chrome-lined barrel, chambered for 3" and 2¾" shells, and comes with a drilled-and-tapped receiver, a five-shim fit system, and Franchi's 7-year warranty. Franchi item number 42040, UPC 650350420401.

Inertia Driven — Clean, Light, Reliable

The Affinity 3 runs the Inertia Driven System: clean, reliable, lightweight operation with easy maintenance. There are no gas ports to foul, no pistons to scrub, and nothing to adjust between load types. That's the single biggest reason the Affinity earns its reputation with hunters who shoot in mud, ice, and salt marsh and don't want to strip a gun every night.

Mossy Oak Bottomland

Mossy Oak Bottomland is the original 1986 pattern and still the most effective concealment in flooded timber, cypress bottoms, and hardwood sloughs — a mud-and-bark palette that breaks up against a tree trunk instead of trying to imitate leaves. On a 20-gauge gun sized for tight quarters, it's a matched set.

Fit You Can Actually Adjust

• Omni Stock Adjustable Fit — five drop and cast adjustment shims included, so the gun can be tuned to your face and shoulder rather than shot as-issued.
• TSA recoil pad — reduces up to 50% of felt recoil for quicker follow-up shots, with a design that won't snag on clothing during the mount.
• 14-3/8" length of pull with the standard 3/4" TSA pad. Optional 3/8" and 1-1/8" pads are available to customize length of pull.

Built for Gloves and Bad Weather

• Oversized bolt release and charging handle — easy operation of the action even with gloved hands.
• Beveled loading port — enlarged and beveled so loading is quick with or without gloves.
• Hard chrome-lined chamber and bore — long-lasting protection from wear and from the elements.
• Chrome bolt and bolt handle — upgraded finish that resists corrosion and looks the part.
• Removable one-piece trigger group — drops out for cleaning and maintenance.
• Drilled and tapped receiver — standard, for quick mounting of optics and accessories.
• Fiber-optic front sight for fast target acquisition.

Who This Shotgun Is For

Duck hunters who want an inertia gun without a flagship price, hunters stepping into 20 gauge for weight and recoil reasons, and anyone who wants a camo autoloader that will get thrown in a boat and still work. The 26" barrel is the versatile length — quick enough for timber, long enough to swing on decoying birds — and it doubles honestly as an upland and dove gun.

Frequently Asked Questions

What's the difference between Affinity 3 and Affinity 3.5?

Chamber. The Affinity 3 is a 3" gun offered in 12 and 20 gauge with IC/M/F chokes. The Affinity 3.5 is 12 gauge only with a 3½" chamber, C/M/F chokes, and an included 3.4 oz stock counterweight. Both share the TSA pad, five-shim kit, 14-3/8" LOP, and 7-year warranty.

Is this the Compact version?

No. Item 42040 is the standard Affinity 3. Franchi's Compact 20-gauge / 26" Bottomland is a separate item number with a shortened stock and four 1/4" LOP spacers.

How does it compare to a Benelli?

Franchi and Benelli are sister brands and share the inertia operating principle. The Affinity is the value-focused expression of it — fewer refinements than an SBE 3, same fundamental action, and a 7-year warranty.

Can I mount a red dot?

Yes. The receiver comes drilled and tapped as standard equipment.
