Description
The Beretta PX4 Storm Type G California is the decocker-only version of Beretta’s roster-compliant PX4, and for a defensive pistol it is the configuration most instructors would pick. The lever drops the hammer and springs straight back to the fire position; there is no safety detent, so there is nothing to leave engaged and nothing to sweep off under pressure.
This is part number JXF9G20CA: 9mm Luger, ten rounds plus one, a 4.10-inch rotating barrel, a Black Bruniton steel slide over a polymer frame with a Picatinny rail, and ambidextrous controls. The Beretta PX4 Storm Type G California is on the California roster and lawful in every other state.
Type G, and why people specify it
- The lever decocks and returns to fire immediately, with no safety position
- No possibility of presenting the pistol and finding a dead trigger
- The same lever position and motion as a Type F, so training transfers
- Preferred by most agencies and instructors who issue hammer-fired pistols
- Everything else on the Beretta PX4 Storm Type G California is identical to the Type F

The rotating barrel, which is the real reason to buy a PX4
- The barrel rotates rather than tilts as the slide cycles
- Part of the recoil impulse becomes rotation about the bore axis instead of muzzle rise
- The pistol tracks flatter and returns to the sights faster than a tilting-barrel equivalent
- Fewer sharp direction changes in the action, which is easier on parts over time
- Recoil energy is unchanged; only its direction is

What roster compliance means, and does not
Appearing on California’s approved handgun roster is a statement about the model’s features, not a restriction on where it can be sold. The Beretta PX4 Storm Type G California is lawful in every state, and buyers outside California get exactly the same pistol with no functional penalty.
It also ships with ten-round magazines, which are lawful everywhere. For practice ammunition, CCI Blazer Brass keeps the cost sensible, and cartridge dimensions and maximum pressures are published by SAAMI.
The double action first shot
The Beretta PX4 Storm Type G California fires the first round with a long, heavy double-action pull and every subsequent round single action. On a defensive pistol the long first pull is a genuine safety feature, and the decocker lets you return to that state without touching the trigger.
Practise the transition from the long first pull to the short second one. Most shooters have it inside a few hundred rounds, and what remains is a single-action trigger that most striker-fired pistols never match.
Setting it up for the house
The rail takes a standard weapon light with no adapter, and on a home-defence pistol that is the accessory that matters most. Ambidextrous controls mean a left-handed shooter needs nothing swapped, and the decocker-only configuration means the Beretta PX4 Storm Type G California can be stored hammer-down with a round chambered and still be ready with a single long trigger pull.
Why this pistol earns its place
- Decocker only, with no manual safety to leave engaged
- A rotating-barrel action that very few makers offer at this price
- The Beretta PX4 Storm Type G California is roster-compliant in California and lawful in every other state
- Fully ambidextrous controls rather than a reversible magazine catch alone
- Beretta’s parts and service network in the United States is as deep as anyone’s
The Beretta PX4 Storm Type G California suits home defence and duty use where a manual safety is the last thing you want. If you would rather have the option of an engaged safety, the Type F version is the same pistol, and where capacity is unrestricted the seventeen-round PX4 is the full-capacity gun.
