About This Part

The mainspring, also known as the hammer spring, is one of the most critical components in the M&P Bodyguard 380's hammer-fired ignition system. This precision-manufactured spring fits over the hammer strut and stores the large amount of energy needed to drive the hammer forward with sufficient force to strike the firing pin and reliably ignite the primer.

When the trigger is pulled in the Bodyguard 380's double-action-only system, the trigger mechanism compresses the mainspring as it cocks the hammer. When the trigger reaches its break point, the mainspring releases its stored energy, driving the hammer forward to strike the firing pin. The mainspring must provide consistent, reliable force to ensure proper ignition under all conditions.

The mainspring also directly affects trigger pull weight - a properly tensioned factory mainspring provides the characteristic double-action trigger pull that Bodyguard 380 owners expect. A worn, weakened, or damaged mainspring can cause light primer strikes, misfires, failure to fire, or inconsistent trigger pull weight. Replacing it with a genuine Smith & Wesson factory part restores proper hammer energy and ensures reliable ignition.

Why Choose Factory OEM Parts?

When it comes to critical ignition components like the mainspring, using genuine Smith & Wesson factory parts ensures:

  • Precise spring rate: Manufactured to exact Smith & Wesson specifications for proper hammer energy
  • Reliable ignition: Correct spring force ensures consistent primer strikes under all conditions
  • Quality materials: Proper spring steel composition ensures durability and resistance to fatigue
  • Perfect compatibility: Designed specifically for M&P Bodyguard 380 pistols with guaranteed fitment
  • Consistent trigger pull: Factory spring rate provides the intended double-action trigger weight
  • Long-lasting performance: Factory springs are built to withstand thousands of firing cycles
  • Safety assurance: OEM parts meet Smith & Wesson's strict quality and safety standards

Installation Notes

Installation of the mainspring requires disassembly of the M&P Bodyguard 380 frame and removal of the hammer assembly. This work should be performed by a qualified gunsmith if you are not experienced with Bodyguard 380 disassembly and reassembly. Proper installation and function testing are critical for safe and reliable firearm operation.

Installation overview:

  1. Ensure the pistol is completely unloaded
  2. Field strip the pistol and remove the slide from the frame
  3. Remove the hammer assembly from the frame
  4. Remove the old mainspring from the hammer strut
  5. Install the new factory mainspring over the hammer strut
  6. Reassemble the hammer assembly and frame
  7. Test hammer function and trigger pull with snap caps before live fire
  8. Verify reliable primer strikes and consistent ignition

Important: Always follow proper firearm safety procedures. Ensure your pistol is unloaded and pointed in a safe direction before performing any maintenance or parts replacement. Verify proper hammer function and ignition after installation.
