Action Enhancement Kit w/ Tank Tread Commander Hammer for Springfield SA-35/ Browning Hi-Power

Description

The Apex Action Enhancement Kit with Tank Tread Commander Hammer delivers a measurable upgrade in trigger control and reliability for your Springfield SA-35 or Browning Hi-Power Mk I / Mk II. Designed specifically for the coastal Florida shooter, this kit addresses the unique demands of salt air, humidity, and daily carry. Every component is machined from billet steel and finished with ArmorLube™ Duplex DLC — a matte black coating that provides exceptional corrosion, abrasion, and wear resistance. This means your trigger and hammer will hold up against sweat, beachside moisture, and frequent handling without rust or finish degradation.

What’s included and what it does:

• Apex Wide Flat Trigger (.31” wide): Inspired by the work of the late Jim Garthwaite, this flat-faced trigger allows your finger to sit lower on the face for improved leverage on pivoting trigger systems. The wider surface spreads pressure evenly, reducing fatigue during extended range sessions and giving you a more positive, repeatable pull. The ArmorLube™ DLC finish resists corrosion far better than standard coatings, making it ideal for EDC in a coastal environment.
• Apex Tank Tread Commander Hammer: This modern take on the classic Commander (ring) hammer eliminates hammer bite thanks to an optimized spur angle and integrated over-cocking limit pad. The checkered cocking surface provides positive traction for your thumb, even with wet or sweaty hands. The hammer hook geometry is precisely matched to the included Mk 1 Balanced Sear, so you get a clean, crisp break without needing to stone or alter engagement surfaces.
• Mk 1 Balanced Sear: Engineered to pair directly with the Tank Tread Commander Hammer. The nose geometry eliminates the need for hand-fitting or stone work, delivering a consistent trigger break right out of the box.
• Balanced Sear Lever & Sear Lever Spring: This is the core reliability upgrade. The original Browning design suffers from inertia-related rotation of the sear lever as the slide goes into battery — a physics limitation that prevented light, crisp pulls without risking hammer follow. By balancing the sear lever and biasing it away from the sear’s contact pad (using the included spring), this kit dramatically reduces hammer follow at lower pull weights. The result: a lighter, cleaner trigger pull that stays safe and reliable.
• Trigger Pin Removal Punch: Included in every kit to prevent frame damage when removing the factory trigger. Watch the installation video before starting.

Fitment: This kit is specifically designed for the Springfield SA-35 and Browning Hi-Power Mk I / Mk II pistols. All components are drop-in compatible with these models, requiring
