The benefits that police are seeing by adapting miniature red dot sights

Miniature Red Dot sights (MRDS) on pistols are quickly being adapted by forward-thinking law enforcement agencies who are discovering the range of benefits offered by adding an optic to a duty pistol. As more data is published, mounting evidence clearly shows that MRDS enhance the safety and accuracy of law enforcement pistols, improve situational awareness and are more effective when used in high stress situations.

The AIMPOINT ACRO-P2 (pictured above) is a popular example of Miniature Red Dot Sights (MRDS) being adopted by modern law enforcement. 

MRDS have been used by special operations forces, tactical teams, and in competitive shooting sports for years. Now with further advancements in durability, battery life, duty holster compatibility and OEM duty pistol compatibility (GLOCK MOS), MRDS have quickly become a viable option for general duty use. As more agencies begin to adopt MRDS optics, the true benefits to usability and police user safety are becoming very apparent.

“In addition to accuracy advantages, MRDS are able to better compensate for physiological responses during high stress situations.”

When the human body is subject to stress, the Sympathetic Nervous System (SNS) initiates a variety of responses that prime the body to defend itself or escape danger. One of the first activations by SNS is to the eyes: our field of vision is increased to it’s maximum, pupils are dilated to intake more visual information, and the Ciliary muscles (the ring of muscles that surround the lens of the eye) contract, which thickens the lens for better distant focus. This reaction has served a critical role in mankind’s survival throughout history, but when operating a firearm, it can make it extremely  difficult to find your sights and acquire sight picture under extreme stress or spontaneous threat1. When using an MRDS, your eyes are able to remain in a more natural and open state, which allows for less reliance on ‘fine’ focus, ultimately better compensating for these involuntary physiological changes. The wider and clearer target picture allows  for a much easier sight to acquire under stress.

Predictably, the human brain also has its own reaction to a stress response triggered by our SNS. Under extreme stress our brain modifies the way it takes in information. Specifically, it prioritizes the volume of information taken in over the accuracy of the information taken in2.  Under high stress, our brains cannot process as much detail in the visual data it takes in, which can cause the mind to make presumptive leaps, or ‘fill in the blanks’3. This is especially true in low-light scenarios4. The human brain can incorrectly complete a pattern or misinterpret an object, like mistaking a floor lamp for a person, or a cellphone for a pistol. This can present an extremely dangerous scenario where police users can make a ‘mistake-of-fact-shooting’, where the police user makes an honest mistake where they believed that use of lethal force was justified. MRDS with their wider focal plane and bright powered red dot allows the police user to greatly increase the amount of information they are able to take in about their surroundings while retaining sight picture.  This additional situational awareness can mitigate some of the presumptive thinking our brains are prone to under extreme stress. In moments where quick decisions need to be made, having additional visual data available to the police user can help make better, more informed decisions and improve both situational awareness and accuracy under stress.

RAMPART offers a complete line of MRDS optics, as well as other pistol attachments and ammunition. 

These are just some of the ways MRDS can help police better protect the public with technology. As more and more agencies adopt MRDS, and as more data is released, the benefits of an MRDS for both public and police user safety are becoming common knowledge. Thier improvements to accuracy, benefits to situational awareness, and better compensation to our physiological responses to stress present a clear advantage over traditional pistol iron sights. MRDS have already been adopted by many agencies across Canada and the United States to great effect. Similarly, agencies are also converting to MOS Pistols in the event they choose to adopt MRDS in the future.

QUICK FACTS : WHY your agency should consider MRDS for general duty Policing:

  • Faster, and more accurate target acquisition
  • Improved usability under stress
  • Improved situational awareness while on target
  • More accurate follow up shots
  • More accurate shots on moving targets
  • Improved low light accuracy
  • Greater accuracy for ageing police users or those with vision issues
