Beretta Px4 Storm
Italian semi-automatic pistol
The Beretta Px4 Storm is a semi-automatic pistol intended for personal defense and law enforcement use.
Design
The Px4 uses a trigger and safety system similar to the Beretta 92 and the Beretta 8000 series, though it is distinguished from its predecessors by its light-weight polymer construction with steel inserts, standard Picatinny rail, and swappable grip backstraps.
Unlike the Beretta 92FS/96FS/M9/M9A1 and the 8000 series pistols, the Px4's trigger guard is rounded rather than squared. The polymer guide rod has a captive slide spring.
The full size (including the Px4 .45 ACP) and Compact versions are manufactured in Italy. The Px4 Subcompact is manufactured in the United States.
Action system
The full size and Compact versions use the same short-recoil, rotating barrel action as the Beretta 8000 series, whereas the Subcompact uses the tilt barrel system.
The full size and Compact versions have a spring-loaded disassembly bar, accessed via recesses on both sides of the frame, which must be grasped and pulled down to release the slide. This is different from the rotating takedown pin of Beretta's previous hammer-fired pistols, which the Px4 Subcompact retains.
The magazine holds the top round directly behind the barrel's breech end so only a slight feed ramp is needed.
This brief starts where responsible research should: with the source description of “Beretta Px4 Storm” as italian semi-automatic pistol. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as italian semi-automatic pistol. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q2294575.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
