[Discussion] Staccato Unveils Full-Size HD P4X 9mm, $3,599, Available July 13

Full-size HD variant arrives July 13

Staccato has announced the HD P4X, a full-size, compensated 9x19mm handgun positioned for duty and professional use. Dealer availability is set for July 13, 2026, and the company lists a starting MSRP of $3,599.

The P4X expands the HD line with a larger steel-frame option built around the same 4-inch compensated barrel used on the compact C4X. Where the C4X emphasizes concealed carry with an aluminum frame, the P4X uses a full-size steel frame and grip for higher capacity and added weight.

Staccato says the pistol will ship in three configurations.

What changes on the P4X

The main differences from the compact HD C4X are frame material, grip size, and magazine capacity. The HD P4X uses a 4140 DLC steel frame rather than aluminum, and its full-size grip takes 18-round magazines instead of the smaller-capacity compact format.

Staccato presents the steel frame as a durability and recoil-control upgrade for hard use. The pistol keeps a flush-fit compensated barrel rather than moving to a longer slide or barrel setup.

Within the broader HD family, the P4X sits as a full-size compensated model alongside the standard HD P4 and the longer 4.5-inch HD P4.5.

Controls, optics, and safety

The HD P4X is configured with fully ambidextrous controls, including an ambidextrous safety and slide stop. The magazine catch is reversible.

For optics, the pistol uses Staccato’s HD HOST mounting system. Magazine compatibility is listed as Glock-pattern, and the package includes two 18-round steel magazines.

Safety features include a mechanical or active firing pin block, intended to add drop safety in duty handling and repeated holstering.

Testing and build details

Staccato says every HD pistol passes federal Ballistic Research Facility standards. The company also describes the HD series as the only 2011 approved for federal use.

The pistol is made in Texas. Staccato positions the HD line as a 2011-family platform developed with input from professional end users, with the P4X specifically aimed at mission-focused and hard-use applications.

Core specifications

The HD P4X is chambered in 9x19mm and uses a 4-inch DLC flush-fit compensated barrel. The trigger is listed at 4 to 4.5 pounds.

Published dimensions are 7.6 inches long, 1.6 inches wide, and 5.5 inches high. Weight is listed at 32.5 ounces. The recoil system is a 3.6-inch flat wire setup.

Other listed features include a steel frame, 18-round capacity, and compatibility with Glock-pattern steel magazines.
