Fully Machined Sear
Pros & cons
What works
- Reduces trigger pull weight by 1.5 pounds—measurable improvement over factory sear
- 0.002" tighter tolerances than Apex Tactical equivalent—enhanced consistency
- 50-52 HRC surface hardness—25,000 cycle service life expectancy
- 3.2 gram weight—optimized mass distribution for smoother operation
Trade-offs
- No included installation tool—requires separate punch set purchase
- Minimal benefit in already upgraded systems—redundant with comprehensive kits
- 45-minute break-in period required—initial engagement may feel gritty

About this product
The Break Point Armory Fully Machined Sear is a CNC-milled drop-in replacement component engineered to optimize trigger performance in S&W M&P series pistols. Developed through precision pistol competition experience, it addresses three critical performance parameters without requiring gunsmith fitting. This component represents our foundational approach to trigger system enhancement.
What is the Fully Machined Sear used for?
This sear reduces trigger pull weight by approximately 1.5 pounds while maintaining factory safety engagement surfaces. It achieves this through precisely calculated engagement angles and surface hardening to 50-52 HRC. The component installs in under 5 minutes using only a punch tool.
How does the Fully Machined Sear compare to Apex Tactical's version?
Our sear provides 0.002" tighter dimensional tolerances than Apex's offering, resulting in more consistent break characteristics across temperature variations. While both reduce pull weight, our heat treatment process extends service life to approximately 25,000 cycles versus Apex's documented 20,000-cycle expectancy. The Apex unit remains adequate for casual use.
What does it weigh and what are the dimensions?
The sear weighs 3.2 grams with overall dimensions of 0.312" x 0.198" x 0.125". These measurements ensure direct compatibility with M&P, M&P M2.0, and Shield series pistols without modification. The mass distribution specifically counters hammer spring tension for smoother operation.
Who is this NOT for?
This component is unsuitable for duty weapons requiring unmodified factory specifications or pistols with aftermarket hammers not matching M&P geometry. It also provides negligible benefit in systems already equipped with our Action Enhancement Kit for CZ P-10 or similar comprehensive upgrades.
What's in the box?
The package contains one machined sear, anti-corrosion treated packaging, and installation reference documentation. Unlike some competitors, we include no redundant components—this reflects our philosophy of targeted upgrades rather than kit redundancy. For full system overhaul, consider our Mass Driver Hammer Kit.
Is the Fully Machined Sear worth it at $45?
At $45, this component delivers measurable performance improvement for competitive shooters seeking reduced pull weight and cleaner break. The cost represents approximately 1/3 the price of a complete trigger kit while addressing the most significant performance bottleneck. For duty or defensive pistols, however, the marginal improvement may not justify the expense.

Frequently asked questions
- Is it compatible with M&P 9 Shield EZ?
- No, the sear is specifically engineered for standard M&P, M&P M2.0, and Shield models with traditional trigger systems. The Shield EZ utilizes a completely different sear geometry and would require separate development. Contact Smith & Wesson for EZ-specific components.
- Does it fit M&P 40 caliber models?
- Yes, the sear is caliber-agnostic and compatible with all M&P frame sizes including 9mm, .40 S&W, and .45 ACP variants. The interface dimensions remain consistent across calibers at 0.312" width. Installation requires standard punch tools and takes approximately 3 minutes.
- How long does shipping take?
- Orders ship within 1 business day via USPS Priority Mail, typically arriving in 2-3 days continental US. International shipments require 7-10 days transit time and may incur additional customs documentation. All components include anti-corrosion packaging for extended transit durability.
- Can I return it if it doesn't fit?
- Returns are accepted within 30 days provided the component shows no installation marks or damage. The sear must be returned in original packaging with all documentation. Given the precise manufacturing tolerances, fitment issues are exceptionally rare—fewer than 0.5% of units require return.
