Beretta A390 ST 12 Gauge Semi-Auto Shotgun, 28" Vent-Rib Barrel, Blued Steel Receiver with Scroll Engraving
The Beretta A390 ST represents the final all-steel evolution of Beretta’s renowned 300-series gas guns. Built in Italy during the early to mid-1990s, this full-size 12-gauge combines a self-compensating gas system that runs anything from 1-ounce target loads to 3-inch magnums with deluxe touches such as factory scroll engraving and a gold-plated trigger. A 28-inch vent-rib barrel capped with an M Mobilchoke tube gives the gun versatile field performance.

Beretta built the A390 ST on a solid steel receiver, giving it added heft and durability compared with later alloy-frame models. The receiver carries tasteful scrollwork on both sides, accenting the deep blued finish.
The gas-operated, self-regulating action automatically adjusts for varying pressures, allowing smooth cycling from light 1-ounce target shells up to 3-inch magnum loads without manual tuning.
Field handling is enhanced by a 28-inch steel barrel with a ventilated rib and single steel bead sight. The Mobilchoke system lets shooters tailor patterns easily; this gun ships with a factory Marked “M” choke for versatile mid-range performance.
The walnut stock features crisp checkering, a straight comb, and a recoil pad that pairs with the 14.4-inch length of pull for comfortable shouldering. A gold-plated single-stage trigger and cross-bolt safety round out the controls, while the right-side charging handle provides familiar operation.
As one of the last steel-receiver 300-series guns before the AL391 era, the A390 ST offers collectors and shooters a proven Italian design with classic styling and modern load flexibility.
