For one of the best tritium sights available for your Smith & Wesson MP, consider the XS Sight Systems Defensive Express tritium front sight. XS Sight Systems is one of the top accessories providers for firearms owners around the country. XS began in 1996 at the inspiration of founder Ashley Emerson. Emerson was unhappy with the poor quality of the available night sights and aperture hunting sights. They were known to be extremely fragile and had many drawbacks in their functionality. Emerson teamed up with a partner to create the company now known for its high-quality sight options.

The front night sight you’ll receive when you order this product contains a tritium insert for ease of use in low-light situations. If you find yourself in a high-stress situation where you need to use your M& P pistol, you will appreciate the speed at which you can acquire your target. The white outline surrounding the tritium insert will draw your eyes to the front sight as well as make it easier for you to use the tritium sight during the day.

The low-profile, snag-free design makes this night sight perfect for both carry and competition firearms. The white ring around the tritium dot permits you to use the sight for long-distance shots if needed or desired. If you’re looking for a long-lasting, sturdy sight that can support you during nighttime shooting with your Smith & Wesson M& P 9, 40, or 45, this XS Sight Systems tritium sight will provide what you need to get the job done in both low light and daylight.
