### Features

The barrel is 4140 steel and drilled for Mobil chokes, so swapping patterns for clay targets or waterfowl is straightforward. At 28 inches it gives a longer sighting plane and tends to track moving targets smoothly.

The polymer stock keeps weight down and holds up to wet conditions without warping. The manual safety is a standard cross-bolt type.

The inertia system delivers smooth cycling and low felt recoil, which helps with quick follow-up shots. It does require loads with enough power to cycle the bolt reliably. Light target loads sometimes need a break-in period before cycling consistently.

## What Customers Say

*AI-generated insights from customer reviews*

Owners of the Alpharms Inertia 1 generally report solid performance across hunting and range use. The cycling behavior gets consistent praise. The inertia system handles a wide variety of shell types once it's broken in, and users note minimal maintenance compared to gas-operated alternatives.

Opinions vary on how it compares to higher-end inertia shotguns, but most agree it performs well for its price point.
