Action Enhancement Trigger Kit for Springfield SA-35

This Action Enhancement Trigger Kit for the Springfield SA-35 replaces the factory fire control group with billet steel components designed to improve trigger geometry, reset, and overall feel. The kit addresses the stock SA-35 trigger’s tendency toward stacking and inconsistent break by pairing a wide flat trigger with a matched hammer and sear set. The result is a shorter, cleaner pull with a defined wall and minimal overtravel.

Compatibility

• Springfield Armory SA-35 (all variants)
• Does not fit Browning Hi-Power or other SA-35 clones
• Includes: Wide Flat Trigger, Hi Tilt Spur Hammer, Mk 1 Balanced Sear, Balanced Sear Lever, Sear Lever Spring, and installation pins

Key Features

• 0.31” wide flat trigger face – lowers finger placement for improved leverage on the pivoting trigger system
• Trigger is DLC coated for corrosion and wear resistance
• Hi Tilt Spur Hammer eliminates need for beavertail clearance pocket; prevents hammer bite via integrated over-cocking limit pad and spur angle
• Mk 1 Balanced Sear nose geometry is pre-matched to hammer hook profile – no stoning or sear engagement adjustment required
• Balanced Sear Lever with matched spring ensures consistent sear movement and clean break
• All components machined from billet steel

Install Difficulty: 3/5

Requires detail disassembly of the SA-35 frame and removal of the factory sear/hammer assembly. Recommended tools: 1/16” punch, brass hammer, bench block, and slave pins. Expect 45–90 minutes for first-time installation. Not drop-in; some fitting may be required on the trigger bar engagement surface.

FAQ

Will this kit work with the factory SA-35 safety?

Yes, the sear and hammer geometry are designed to function with the factory ambidextrous safety. However, the safety engagement should be checked after installation to ensure full engagement with the sear lever.

Does the trigger weight change?

The kit reduces trigger pull weight by approximately 1–1.5 lbs compared to factory specification. The break becomes more defined with a shorter reset. The hammer spring must remain factory SA-35 specification for reliable ignition.

Is this the same as the Apex Action Enhancement Kit for the Springfield XD series?

No. This kit is specific to the SA-35’s pivoting trigger system and uses a different sear lever geometry. Do not use components from the XD or M&P kits in this platform.
