The Smith & Wesson M&P Shield 9mm is a popular and reliable concealed carry pistol. However, many owners find the factory trigger somewhat underwhelming. A trigger upgrade can significantly improve the shooting experience, making the pistol more accurate and enjoyable to shoot. This guide dives deep into the world of M&P Shield 9mm trigger upgrades, exploring different options, installation processes, and the potential benefits and drawbacks.
Understanding the Factory Trigger
Before exploring upgrades, let's examine the standard M&P Shield 9mm trigger. It's generally characterized by a relatively long pull with noticeable take-up and a somewhat gritty feel. While functional, this design prioritizes safety over a crisp, clean break. This longer, heavier pull can affect accuracy, especially for new shooters or those accustomed to lighter triggers. The factory trigger's characteristics are a trade-off between safety and performance, and many users want to adjust that balance.
Key Characteristics of the Factory Trigger:
- Long Trigger Pull: The distance from the initial press to the break is longer than many aftermarket options.
- Gritty Feel: The trigger pull often feels rough, due to friction in the mechanism.
- Heavy Pull Weight: The force required to break the trigger is heavier than some prefer.
- Noticeable Take-Up: There's a discernible amount of slack before the trigger engages.
