The M3500 uses Stoeger’s inertia-driven action with a rotating bolt head. It is chambered for 2.75, 3, and 3.5 inch shells and does not require adjustment to switch loads. Ejection is to the right, and the listed capacity is 4+1 with 3 in shells.
The 28 in vent-rib barrel provides a long sighting plane, and the red fiber-optic front bead offers a bright aiming reference. The barrel is threaded for interchangeable choke tubes to adapt the pattern to different field conditions.
The stock and forend are synthetic with molded grip texturing for secure handling. A black rubber recoil pad with the Stoeger S logo is fitted at the butt. Sling attachment points include a rear swivel at the stock toe and a forward swivel on the knurled magazine cap.
Camouflage finish extends across the stock, receiver, and barrel; the magazine cap is plain metal. Length of pull measures 14.5 in. This shotgun is manufactured in Turkey.
