Smith & Wesson 160228 Model 351PD .22 WMR 1.88" Revolver, 7-Round, HiViz Fiber Optic Sight

The Smith & Wesson Model 351PD is a seven-shot J-Frame revolver chambered in .22 WMR and built around a lightweight aluminum-alloy frame, 1.88-inch barrel, exposed hammer, and HiViz fiber-optic front sight. Its defining distinction is the combination of a small J-Frame format with seven-round rimfire magnum capacity rather than the five-shot centerfire layout more commonly associated with compact Smith & Wesson revolvers.

The .22 WMR chambering keeps recoil comparatively light while providing more velocity and energy than .22 LR from a similarly sized handgun. Paired with the lightweight frame and short barrel, the 351PD is a compact revolver configuration that emphasizes low mass, simple operation, and higher cylinder capacity.

Seven-Shot J-Frame Configuration

The Model 351PD uses a seven-round cylinder within Smith & Wesson's J-Frame architecture. That higher cylinder capacity is possible because the .22 WMR cartridge has a smaller diameter than the centerfire cartridges used in many five-shot J-Frame models.

This gives the 351PD a different balance of size and capacity while retaining the compact frame dimensions associated with the J-Frame family.

.22 WMR Chambering

The revolver is chambered for .22 Winchester Magnum Rimfire. Compared with .22 LR, the .22 WMR cartridge uses a longer case and is generally loaded to higher velocities, giving it different ballistic characteristics while remaining relatively manageable in a lightweight revolver.

The cartridge is not interchangeable with .22 LR unless specifically supported by a separate cylinder, so ammunition should be matched to the .22 WMR chambering marked on the firearm.

Lightweight Aluminum-Alloy Frame

The 351PD uses an aluminum-alloy frame rather than an all-steel J-Frame construction. Reducing frame mass is one of the principal design differences of the PD configuration and helps keep the revolver light without changing its basic operating system.

The matte black finish gives the frame a subdued exterior, while the cylinder and barrel complete the compact revolver layout.

Double-Action / Single-Action Operation

An exposed hammer allows the 351PD to be fired in either double-action or manually cocked single-action mode.

That separates it from enclosed-hammer J-Frame models such as the Model 640, which are configured primarily around double-action operation. The exposed hammer preserves the traditional firing sequence and manual cocking option found on classic Smith & Wesson revolvers.

1.88-Inch Barrel

The 1.88-inch barrel keeps the revolver compact and maintains the short-profile proportions associated with small-frame Smith & Wesson revolvers.

The shorter barrel reduces overall length, while the seven-shot cylinder and full J-Frame grip area preserve practical handling within the small revolver format.

HiViz Fiber-Optic Front Sight

The 351PD is equipped with a HiViz fiber-optic front sight that provides a bright visual reference against a wide range of backgrounds.

That sighting system is a meaningful upgrade over a plain black front blade, particularly on a short-barreled revolver where rapid sight acquisition is often more relevant than fine target adjustment.
