The Franchi Affinity 3 is an inertia-driven, semi-automatic 20 Gauge shotgun with a 26-inch barrel and a 3-inch chamber. It has an A-Grade satin walnut stock and fore-end, and it holds 4+1 shells when loaded. The inertia system cycles the action without tapping gas off the barrel, which keeps the mechanism simple.

Owners of the Affinity 3 in 20 Gauge generally praise the inertia system for cycling a range of shell loads reliably without needing adjustment, which is the main draw of Franchi's inertia guns. A few owners note the action needs to be kept reasonably clean to stay consistent, which is typical of inertia-driven shotguns in general.

In the field, the 20 Gauge Affinity 3 is often chosen for its lighter carry weight next to a 12 Gauge counterpart, and the satin walnut stock gets compliments for looking sharper than the synthetic-stocked versions. Felt recoil is mild for the gauge, which owners say makes it comfortable through a full day of upland hunting or a dove shoot.

Value opinions lean positive: buyers moving up from a pump gun see the semi-auto cycling as worth the price step, though some mention that aftermarket parts and accessories are more limited for the 20 Gauge Affinity than for the more common 12 Gauge version.
