Description
There is something to be said for a shotgun that does one thing and does it well. The Henry H015-20 is a break-action single shot in 20 gauge, built with a blued steel receiver, a 26-inch round blued barrel, and a checkered American walnut stock with a pistol grip wrist and solid rubber recoil pad. It weighs in around 6.6 pounds with an overall length of 41.5 inches, so it swings quick on flushing birds and never feels like a chore on a long walk through the uplands. A brass bead up front keeps the sight picture simple, just the way a field gun should be.
How the H015-20 Handles in the Field
The 3-inch chamber runs both 2-3/4 and 3-inch shells, and the barrel is internally threaded for Rem-Choke style tubes with a Modified choke included. That Modified constriction patterns well in that 25 to 45 yard window, which covers doves, quail, grouse, pheasant, rabbits, and squirrels without needing to swap anything. When you do want a tighter or more open pattern, screwing in a different tube takes seconds. One nice touch over a lot of older single shots: when you break the action open, spent hulls eject fully rather than just lifting partway out, so reloading is quicker than you might expect from a one-shooter.
Built Around Henry's Proven Single Shot Action
This shotgun shares its action with Henry's single shot rifle line, using a rebounding external hammer that cannot contact the firing pin unless the trigger is pulled. An interlock system also prevents opening or closing the action while the hammer is cocked. There is no manual safety to fumble with, which keeps operation about as straightforward as it gets and makes this a great platform for teaching fundamentals to a first-time shotgunner.
Why the Henry Single Shot 20 Gauge Sticks Around
Between the walnut and blued steel looks, the made-in-USA build quality, and the mild-mannered 20 gauge chambering, the H015-20 is the kind of gun that gets handed down. Whether it is your grouse gun, your truck gun, or the one your kid learns on, it earns its keep.

Frequently Asked Questions
Does the Henry H015-20 accept interchangeable choke tubes?
Yes. The barrel is internally threaded for Rem-Choke style tubes, and a Modified choke comes installed from the factory. Modified is a great all-around choice for birds and small game at 25 to 45 yards, and you can swap in tighter or more open tubes depending on what you are hunting.
Can the H015-20 shoot both 2-3/4 inch and 3 inch shells?
It can. The chamber is cut for 3-inch shells, so it handles standard 2-3/4 inch loads as well as 3-inch magnums. For most range sessions and upland hunts, lighter 2-3/4 inch loads are plenty and keep recoil mild in this 6.6 pound gun.
Is there a manual safety on the Henry Single Shot 20 gauge?
No, there is no manual safety switch. Instead, it uses a rebounding hammer that physically cannot contact the firing pin unless the trigger is pulled, plus an interlock that prevents opening or closing the action while the hammer is cocked. It is a simple, time-proven setup that keeps operation uncomplicated.
Is the Henry H015-20 a good first shotgun for a new shooter?
It is one of the better choices out there for that job. The single shot break action forces good habits, the 20 gauge chambering keeps recoil manageable, and the rubber recoil pad helps soften things further. There is nothing complicated to learn, which lets a new shotgunner focus on fundamentals.
