Performance Spring Set for Hellcat and Hellcat Pro

This spring set replaces the factory trigger return spring and sear spring in the Hellcat and Hellcat Pro. The balanced pair reduces trigger pull weight to a consistent 4.75–5.5 lbs while maintaining reliable primer ignition. The sear spring includes a felt core that acts as a vibration attenuator, reducing harmonic fatigue and extending service life. Intended for shooters who want a lighter pull without modifying geometry or sear engagement surfaces.

Compatibility

• Springfield Hellcat (all variants)
• Springfield Hellcat Pro (all variants)
• Does not fit Hellcat RDP compensated models without verifying sear housing dimensions

Key Features

• Drop-in replacement – no fitting or sear engagement adjustment required
• Trigger pull weight: 4.75 – 5.5 lbs (as measured with factory trigger)
• Sear spring with felt core dampens vibration and reduces spring fatigue over time
• Manufactured in the USA from high-grade spring steel
• Includes: trigger return spring + sear spring

Install Difficulty

2 / 5 – Moderate. Requires detail stripping the fire control unit to access the sear spring and trigger return spring. Tools needed: 1/16” punch, small hammer or mallet, slave pin (or paperclip) for trigger bar assembly. Armorer’s block recommended but not required. Allow 20–40 minutes for first-time install.

FAQ

Will this spring set work with an aftermarket trigger shoe?

Yes. The springs are compatible with factory and aftermarket trigger shoes that use the standard Hellcat trigger return spring pocket. If using a shoe with a different spring channel depth, verify the spring sits flush without binding.

How often should the felt core be oiled?

Add one drop of light machine oil (CLP or similar) to the felt core every 3,000–5,000 rounds. This maintains the vibration-dampening effect and extends sear spring life under live fire.

Does this set include the striker spring?

No. This is a two-spring set (trigger return spring and sear spring only). The factory striker spring is retained. If you want a lighter striker spring, order separately.
