Description
Plenty of folks asked Beretta for a 20 gauge version of the A300 Ultima Patrol, and the company delivered. This gray model takes everything that made the 12 gauge Patrol such a hit and trims it down to a 6 pound package that shoulders quicker, swings faster, and stays comfortable through a long training session. The gas-operated action soaks up recoil that a pump gun would send straight into your shoulder, so follow-up shots come back on target in a hurry. With modern loads like Federal's Flitecontrol buckshot now available in 20 gauge, this bore size has become a legitimate choice for home defense rather than a compromise.
What Makes the A300 Ultima Patrol 20 Gauge Easy to Run
Beretta built this gun around fast handling under pressure. The bolt handle and bolt release are extended, the loading port is opened up for quicker tube stuffing, and the safety is oversized and reversible for lefties. The 19.1 inch barrel wears ghost ring sights that are quick up close and precise enough for slugs, while a factory-installed 7-slot Picatinny rail handles red dots. The slimmed forend carries aggressive texturing and three M-LOK slots, the natural spot for a weapon light. It also accepts aftermarket rails and optic mounts made for the 1301 Tactical, so the accessory well runs deep.
Sized Right for More People in the House
The stock ships with a 13 inch length of pull and drops to 12 inches by pulling the spacer, which means smaller-framed family members can run this gun comfortably right alongside you. Integrated QD sling cups are molded in, so slinging up takes seconds. The extended magazine tube holds seven rounds plus one in the chamber, and the 3 inch chamber gives you flexibility on load selection. The Mobilchoke system with an Improved Cylinder tube installed lets you tune patterns to your preferred buckshot. All told, this is a full-featured patrol shotgun that more members of the household can shoot well, and that counts for a lot.

Frequently Asked Questions
Is 20 gauge enough for home defense compared to the 12 gauge A300 Ultima Patrol?
For most situations inside the home, yes. Modern defensive loads like Federal's Flitecontrol 20 gauge buckshot pattern tightly at typical indoor distances and carry serious energy. You trade a bit of payload for noticeably lighter recoil and a gun that weighs about two pounds less than the 12 gauge version, which makes training more pleasant and follow-up shots faster.
Can I mount a red dot on the A300 Ultima Patrol 20 gauge?
Yes. It comes from the factory with a 7-slot Picatinny rail on the receiver, so any standard Picatinny-mounted optic bolts right up. It is also compatible with aftermarket rails and optic mounts made for the Beretta 1301 Tactical, including low-mount plates that let you co-witness with the ghost ring sights.
Can the stock be adjusted for smaller shooters?
It can. The gun ships with a 13 inch length of pull, and removing the included spacer brings it down to 12 inches. That short pull, combined with the 6 pound weight and soft-cycling gas system, makes this one of the easier defensive shotguns for smaller-framed folks to run well.
Does the A300 Ultima Patrol 20 gauge accept choke tubes?
Yes, the 19.1 inch barrel uses Beretta's Mobilchoke system and comes with an Improved Cylinder tube installed. IC is a solid all-around constriction for buckshot, but you can swap tubes to tighten or open your patterns. It is worth patterning your chosen defensive load at realistic distances to see how it performs.
