Design and Construction

The Smith & Wesson Model 351 PD is part of the company’s AirLite PD series, which signifies its use of advanced materials to reduce weight without compromising strength. The “PD” stands for “Personal Defense,” indicating its intended role. The revolver features a 1.875-inch barrel and a seven-shot capacity, which is generous for its size, especially considering the caliber it fires.

Constructed with a lightweight aluminum alloy frame and a titanium cylinder, the 351 PD weighs in at a mere 10.8 ounces when unloaded. This makes it one of the lightest revolvers on the market, a significant advantage for a weapon meant to be carried for extended periods. The use of these materials also ensures that the revolver is resistant to corrosion, an essential feature for a firearm that may be exposed to various environmental conditions.

Caliber
It is chambered for the .22 Winchester Magnum Rimfire (.22 WMR) cartridge. This caliber provides a balance of low recoil and effective terminal performance for self-defense and small game hunting within its effective range.

Action
This revolver operates on a double-action mechanism, meaning it can be fired simply by pulling the trigger without the need to manually cock the hammer. This feature is beneficial in high-stress defensive situations where simplicity and speed are paramount.

Capacity
It has a seven-round capacity, which is relatively high for a revolver of its size and caliber, providing a good balance between firepower and size for self-defense situations.

Sights
Equipped with a HiViz fiber optic front sight and an adjustable rear sight, the Model 351 PD offers enhanced sight acquisition in various lighting conditions, which is crucial for accurate shot placement.

Grip

Performance and Use

The .22 WMR cartridge offers a balance of power and controllability. It is capable of delivering effective performance for self-defense, with less recoil and noise compared to larger calibers, making it a good choice for those sensitive to these factors. The revolver’s fixed sights are adequate for close-range engagements, which is where a compact revolver like the 351 PD is most likely to be employed.

It’s important to note, however, that while the .22 WMR is effective within its limitations, it does not offer the stopping power of larger calibers. Thus, the 351 PD is best suited for those who prioritize ease of carry and handling over maximum firepower.

My Personal Maintenance Routine Smith & Wesson Model 351 PD

Gun cleaning supplies from Hoppe's 9 on a wooden tray, possibly for maintaining a Smith & Wesson Model 351 PD.
  • Safety Check: Always begin by ensuring the revolver is unloaded. Open the cylinder and visually inspect each chamber to confirm that no ammunition is present.
  • Disassemble for Cleaning: Refer to your Smith & Wesson Model 351 PD manual for instructions on disassembling your revolver for cleaning. Typically, this involves opening the cylinder and removing it from the frame for easier access to all parts.
  • Clean the Barrel: Use a bore brush attached to a cleaning rod to scrub the inside of the barrel. Apply a solvent specifically designed for firearms to the brush. After scrubbing, pass a clean patch through the barrel to remove any residue and solvent. Repeat with clean patches until they come out clean.
  • Clean the Cylinder Chambers: Similar to the barrel, use a bore brush and solvent to clean each chamber in the cylinder. Follow with clean patches until they emerge without residue.
  • Clean the Action: Apply solvent to a nylon brush or a cloth to clean the moving parts of the action, including the trigger assembly and hammer mechanism. Be careful to remove all grime and powder residue.
  • Inspect and Lubricate the Cylinder and Ejector: Check the cylinder and ejector for any signs of wear or damage. Apply a small amount of gun oil to these parts to ensure smooth operation.
  • Lubricate Moving Parts: Apply a drop of gun oil to all moving parts, including the hammer, trigger mechanism, and any other areas as specified in your firearm’s manual. This helps in reducing friction and wear.
  • Wipe Down the Frame and Exterior: Use a clean, soft cloth to wipe down the exterior of the gun, including the frame, barrel, and cylinder. This not only removes any fingerprints and potential corrosives but also allows you to inspect the surface for any signs of wear or damage.
  • Reassemble Your Revolver: Once all parts are clean and lubricated, carefully reassemble your Smith & Wesson Model 351 PD according to the manufacturer’s instructions.
  • Function Check: After reassembly, perform a function check to ensure the revolver operates correctly. This includes checking the cylinder rotation, hammer operation, and trigger pull in both double-action and single-action modes. Do not load the revolver during this check.

Safety Tips

  • This fundamental rule of gun safety ensures that you maintain a high level of caution in handling your firearm. Even if you believe it to be unloaded, treating it as loaded will prevent accidental discharges.
  • A safe direction means that even if the gun were to go off, it would not cause injury or damage. This direction may change depending on your surroundings, so always be aware of where your gun is pointed.
  • Your finger should rest outside the trigger guard until you are actually ready to fire. This prevents accidental discharges, which could occur if you were startled or lost your balance.
  • Bullets can penetrate through walls and other materials. Be sure of your target and what is beyond it to avoid unintentional harm or damage. This is crucial not only at the range but also in home defense situations.
  • When not in use, ensure your Smith & Wesson Model 351 PD is stored in a secure location, inaccessible to unauthorized users, especially children. Use gun safes, locks, or other security measures to prevent unauthorized access.
