My M&P 40 is a fantastic pistol, but adding a Trijicon RMR red dot sight took it to a whole new level. This sight is like a built-in performance upgrade, making my M&P 40 faster, more accurate, and ready for any situation.

Precision on a Pistol:

Here's a quick rundown of the Trijicon RMR's specs that make it perfect for the M&P 40:

Adjustable LED red dot: Fine-tune the dot intensity for various lighting conditions, ideal for both target shooting and self-defense.

Ruggedized machined housing: Built to take the recoil of the M&P 40 and more, ensuring reliability.

Trijicon tritium illumination (select models): No batteries required, the red dot is always on and visible in low light (tritium models only).

Multiple sight picture options: Choose between a 3.25 MOA or 6.5 MOA dot size depending on your desired balance of precision and speed.

Compact footprint: Mounts securely to the M&P 40's slide without adding excessive bulk for concealed carry.

M&P 40 Perfected:

The Trijicon RMR elevates my M&P 40 in several ways:

Lightning Fast Aiming: The red dot allows for significantly faster target acquisition compared to iron sights, crucial for both competition and self-defense scenarios.

Enhanced Accuracy: Focus on the target, not the front sight, for improved shot placement.

Daylight and Low-Light Capability (tritium models): The adjustable red dot works well in various lighting conditions, and Trijicon models offer self-illumination for low-light situations.

Maintains Situational Awareness: The compact design allows for both-eyes-open shooting, keeping you aware of your surroundings while on target.

A Few Considerations:

While undeniably impressive, the Trijicon RMR does have a couple of things to consider for use on an M&P 40:

Cost: Trijicon sights are a premium investment, and the RMR is no exception.

Iron Sight Replacement: Mounting the RMR typically replaces your factory iron sights. Back-up iron sights are available, but they add cost and bulk.

Dot Size Choice: Picking between a 3.25 MOA or 6.5 MOA dot depends on your shooting style and intended use.

My M&P Transformed:

Since adding the Trijicon RMR, my M&P 40 has become an extension of myself. The red dot is incredibly fast to pick up, and the adjustable brightness lets me use it in any lighting. The tritium models offer amazing low-light visibility, and the overall build quality feels indestructible.

The Online Buzz:

Online forums for M&P 40 owners are filled with discussions about the Trijicon RMR. While the price is a common point of discussion, users rave about its durability, speed, and low-light capabilities (with tritium models). Many consider it the gold standard for red dot sights on M&P pistols.

If you're looking to unlock the full potential of your M&P 40 and take your shooting to the next level, the Trijicon RMR is a fantastic choice. The upfront cost is significant, but the boost to performance and versatility makes it a worthwhile investment for serious M&P 40 users.
