Action Enhancement Trigger Kit for M&P
About this product
What is the Action Enhancement Trigger Kit for M&P? It is a precision-engineered drop-in trigger system designed specifically for Smith & Wesson M&P (9mm/.40S&W) pistols that reduces pull weight to a consistent 5.0 to 5.5 pounds while shortening pre-travel and over-travel by approximately 20%. Developed by Break Point Armory, this kit maintains factory safety standards with a center-mounted pivoting safety mechanism and requires no gunsmithing for installation, making it ideal for duty carry and competitive shooting applications where reliability and predictable performance are non-negotiable.
What is the Action Enhancement Trigger Kit for M&P used for?
This kit is used to upgrade the factory trigger on Smith & Wesson M&P pistols to achieve a smoother, more consistent breaking action with reduced travel distances. It delivers a measured 5.0 to 5.5 lb pull weight (approximately 1 lb reduction from stock), decreases pre-travel and over-travel by 20%, and maintains all factory safety functions, making it suitable for both defensive and competition use where shot-to-shot consistency matters.
How does the Action Enhancement Trigger Kit compare to the Apex Tactical Forward Set Sear & Trigger Kit?
The Break Point Armory kit produces a cleaner break with 0.2 lb less variance in pull weight across 100-cycle testing compared to the Apex Tactical kit. While the Apex kit offers a slightly lighter pull at 4.5 lb, the Break Point Armory kit provides better consistency in reset timing—averaging 0.15 seconds per reset cycle—and retains the factory pivot safety design, which some operators prefer for duty carry redundancy.
What does it weigh and what are the dimensions?
The complete kit weighs 42 grams (1.48 oz) and packages components in a 75mm x 50mm x 15mm (2.95" x 1.97" x 0.59") foam-lined case. Individual parts include a trigger shoe measuring 28mm in width, a sear with a 12mm engagement surface, and a return spring with 10 active coils—all machined to tolerances within ±0.05mm.
Who is this NOT for?
This kit is not for M&P pistols with the older 1/16" sear plunger and spring configuration, which require upgrading to a modern sear housing block first. It is also unsuitable for shooters seeking a sub-4.0 lb competition trigger, as its design prioritizes reliability and safety over extreme lightening. For those applications, consider the Action Enhancement Kit for CZ P-10, which offers a 3.5 lb pull option.
What's in the box?
The kit includes one precision-machined trigger shoe, one hardened sear, one trigger return spring, one sear spring, and one pivoting safety lever—all drop-in components requiring zero fitting. Each piece is individually bagged and accompanied by a detailed 4-page installation guide with torque specifications (8-10 in-lb for grip module screws) and a link to our sear housing block upgrade tutorial.
Is the Action Enhancement Trigger Kit worth it at $110?
At $110, this kit delivers measurable performance gains for shooters prioritizing consistency over ultralight pulls, costing $25 less than the Apex Tactical equivalent while offering superior break repeatability. The 20% reduction in travel distances and 1 lb pull weight reduction translate to faster split times—verified at 0.18 seconds between shots in USPSA drills—making it a high-value upgrade for serious M&P users who demand reliability without gunsmithing fees.

Pros & cons
What works
- Reduces trigger pull to 5.0-5.5 lb — 1 lb lighter than factory
- Cuts pre-travel and over-travel by 20% — measurable in 0.1" reduction
- Maintains factory safety pivot — zero compromise on drop safety
- Drop-in installation — no fitting, 15-minute install time
Trade-offs
- Requires 1/8" sear plunger system — incompatible with older 1/16" M&Ps without $35 sear block upgrade
- Not for sub-4.0 lb competition triggers — limits extreme speed shooting applications
- Reset audibility is 5 decibels quieter than Apex kit — some users miss tactile feedback

Frequently asked questions
- Is it compatible with M&P 2.0 models?
- Yes, it is fully compatible with all M&P 9mm and .40S&W models, including 1.0 and 2.0 versions, provided they use the 1/8" sear plunger system. Installation requires no modification and takes approximately 15 minutes with basic punch set and screwdriver.
- Does this work with aftermarket sleeves?
- It functions with most aftermarket sleeves, but we recommend using only OEM or verified aftermarket sear housing blocks from vendors like Brownells to ensure proper spring alignment and safety function. Improper mating can increase reset time by 0.05 seconds.
- Can I return it if it doesn't fit?
- Returns are accepted within 30 days if the kit is uninstalled and undamaged, but we strongly advise confirming your sear plunger size (1/8" required) before purchase. Customers with 1/16" systems should first acquire a modern sear housing block, available from MidwayUSA or Brownells.
- How long does shipping take?
- Standard shipping via USPS Priority Mail takes 2-3 business days continental U.S., with international orders requiring 7-10 days via DHL Express. All kits ship within 24 hours of order confirmation from our Nevada facility.
