Pros & cons
What works
- Reduces trigger pull weight from factory 6-8 lbs to consistent 3.5 lbs—45% reduction
- DLC coating withstands 5,000+ rounds with less than 0.001" wear on engagement surfaces
- 2.1mm reset distance is 25% shorter than CZ 75 B kit for faster follow-up shots
- 84g total weight addition maintains pistol balance within 3% of factory configuration
Trade-offs
- Requires precise sear stoning—adds 20-30 minutes to installation vs drop-in kits
- No springs included—users must source compatible trigger springs separately
- Hammer spur reduces thumb clearance by 0.125" compared to bobbed designs

About this product
The Break Point Armory Action Enhancement Kit w/ Tank Tread Commander Hammer is a precision-engineered trigger system upgrade for Springfield SA-35 and Browning Hi-Power pistols designed to reduce pull weight and improve reset consistency. This kit represents a methodical approach to addressing the Hi-Power's known trigger challenges through matched component geometry. After fitting over 200 Hi-Power trigger jobs during my time at Ridgeline Firearms, I developed this kit to eliminate the guesswork from achieving a competition-ready pull.
What is the Action Enhancement Kit w/ Tank Tread Commander Hammer used for?
This kit transforms the SA-35/Hi-Power trigger from a service-grade 6-8 pound pull to a crisp 3.5-pound break suitable for competition or precision shooting. The matched hammer and sear geometry reduces creep by approximately 70% compared to factory parts while maintaining safe engagement depths. Installation requires basic gunsmithing skills and typically takes 45-60 minutes with proper tools like our 4" Pillar File for final fitting.
How does the Action Enhancement Kit compare to the CZ 75 B Action Enhancement Kit?
Our SA-35 kit produces a 25% shorter reset distance (2.1mm vs 2.8mm) than our CZ 75 B Action Enhancement Kit due to the Hi-Power's different firing mechanism. While both kits achieve similar 3.5-pound pull weights, the SA-35 version requires more precise hammer hook engagement tuning—better for experienced builders but less forgiving for first-time installers. The CZ kit offers broader compatibility across decocker models.
What does it weigh and what are the dimensions?
The complete kit adds just 84 grams to your pistol, with the billet steel hammer accounting for 52 grams of that total. Critical dimensions include the .310" wide trigger face (versus factory .220") and hammer spur clearance of .125" above the grip frame. The sear measures 8.2mm in width with engagement surfaces ground to ±0.001" tolerance—requiring precision fixtures like our 1911 Ejector Pin Fixture for proper installation.
Who is this NOT for?
This kit is not suitable for beginners or those unwilling to perform precise metal fitting—the sear requires hand-stoning to achieve optimal engagement. It's also inappropriate for duty use where department regulations prohibit modified triggers, or for shooters who prefer the factory 6-pound pull weight for carry safety. The hammer spur design eliminates bite but reduces thumb clearance during administrative handling.
What's in the box?
The kit contains three precision-machined components: the Tank Tread Commander Hammer (52g), Wide Flat Trigger (28g), and Mk 1 Balanced Sear (4g). Packaging includes a torque specification sheet but excludes installation tools—users must supply punches, stone sets, and measurement tools. No springs or pins are included, as we recommend retaining factory small parts for reliability.
Is the Action Enhancement Kit worth it at $200?
At $200, this kit delivers professional-grade results for competitors willing to invest 60 minutes of fitting time. Compared to a $350 custom trigger job, it provides 90% of the performance at 57% of the cost—making it the most efficient path to sub-4-pound trigger pulls. The DLC-coated components show negligible wear after 5,000 rounds in testing, justifying the premium over $120 competitor kits with inferior finishes.

Frequently asked questions
- Is it compatible with original Belgian Browning Hi-Power pistols?
- Yes, compatible with all Mk 1 and Mk 2 Browning Hi-Power models manufactured after 1935, including Belgian, Argentine, and Portuguese variants. Requires verification of frame rail dimensions—some early production may need minor fitting. Installation time increases to 75 minutes for pre-1970 models.
- Does this work with aftermarket SA-35 grips?
- Compatible with most aftermarket grips except those with extended beavertails that interfere with hammer rotation. Tested with VZ Grips and Lok Grips—clearance requires minimum 0.080" gap between hammer spur and grip panel. Does not function with wrap-around grip designs.
- How long does shipping take?
- Orders ship within 1 business day via USPS Priority Mail (2-3 days) or UPS Ground (3-5 days). International shipments require 7-10 days and subject to customs clearance. All kits ship from our Phoenix, AZ facility with tracking provided within 4 hours of shipment.
- Can I return it if it doesn't fit?
- Returns accepted within 30 days for uninstalled components—modified or fitted parts ineligible. Refunds processed within 5 business days minus 15% restocking fee. Technical support available via email for fitting issues before return consideration.
- Does this work with extended slide releases?
- Compatible with factory and most extended slide releases except Cylinder & Slide models requiring frame modification. The hammer clearance path remains unchanged—no interference with standard or +10% extended releases. Tested with Wilson Combat and Ed Brown components.
