Description
The CZ-USA 1020 G2 20 Gauge 28″ 4 + 1 Gloss Black/Walnut is a semi-auto shotgun built for lightweight, reliable performance in the field and on the range. It ships with a 28″ barrel and accepts 3″ shells, and the design uses CZ’s inertia operating system adapted to a smaller 20ga receiver. The shotgun includes five CZ Active extended chokes and a drilled & tapped receiver with a Weaver-style rail supplied in the box. Controls are oversized for straightforward operation and it comes fitted with a walnut stock and a bead front sight.

Key Features
- Inertia-Driven Action: CZ’s inertia operating system is adapted to a compact 20ga receiver, reducing felt recoil and improving cycling reliability with everything from light target loads to heavy 3″ magnums — why it matters: you get a soft-shooting gun that runs dirty and never short-strokes.
- Extended Choke Set: Ships with five CZ Active extended chokes (C, IC, M, IM, F) plus a choke wrench — why it matters: you can dial in pattern density for anything from dove fields to turkey woods without buying extra tubes.
- Drilled & Tapped Receiver: Receiver is pre-drilled and tapped, and includes a Weaver-style rail in the box — why it matters: mounting a red dot or scope takes minutes, not gunsmith time.
- Oversized Controls: Oversized bolt handle, bolt release, and safety button — why it matters: gloved hands in cold weather can still run the gun without fumbling.
- Walnut Stock with Recoil Pad: Gloss-finished walnut stock with a ventilated recoil pad — why it matters: looks classic, but the pad tames the snap from 3″ shells.
Who It’s For
This shotgun is for the upland hunter who wants a lightweight 20ga that carries all day, or the clays shooter who wants a reliable semi-auto without the sticker shock of a high-end Italian gun. It’s also ideal for smaller-framed shooters or anyone stepping down from 12ga who still wants 3″ capability for geese or turkey.
Pros and Cons
- Pros: Lightweight at 6.2 lbs; inertia system runs clean with low maintenance; five extended chokes included; drilled/tapped for optics; walnut stock looks better than synthetic at this price point.
- Cons: Inertia system can be sensitive to light loads below 1,150 fps — per CZ-USA specs, break-in with 1,200+ fps loads is recommended for first 100 rounds. Also, the glossy finish shows scratches more than matte.

FAQ
What shells does the CZ-USA 1020 G2 cycle reliably?
Per CZ-USA specs, the inertia system cycles best with shells at 1,200 fps or higher for the first 100 rounds. After break-in, it handles 2.75″ target loads down to 1,150 fps and all 3″ magnums. Avoid light 1,100 fps loads during break-in.
Can I mount a red dot on the 1020 G2?
Yes. The receiver is drilled and tapped, and the box includes a Weaver-style rail. You can mount most red dots or low-power scopes with standard Weaver rings. No gunsmithing needed.
Does the 20ga version kick less than a 12ga?
Yes, but the 6.2 lb weight means 3″ loads still have noticeable recoil. The ventilated recoil pad helps. For target loads, it’s very mild. According to CZ-USA, the inertia system reduces felt recoil by about 15% vs. fixed-breech guns.
What chokes are included?
Five CZ Active extended chokes: Cylinder, Improved Cylinder, Modified, Improved Modified, and Full. They are steel-shot rated. A choke wrench is included.
