For years, the debate raged: iron sights versus optics on handguns. Now, the question isn’t if you should run a red dot, but which red dot sight is right for you. As a long-time shooter and outdoor writer, I’ve seen the evolution firsthand. The benefits are clear – faster target acquisition, improved accuracy, and enhanced visibility, especially for those of us with aging eyes. This guide will break down everything you need to know about pistol red dots, from understanding the differences between an RMR CC vs RMR to finding the best sights for M&P Shield Plus and everything in between. We’ll cover everything from MOA selection to co-witnessing and even mounting options.
Let’s start with the basics. “RMR” stands for Ruggedized Miniature Reflex sight, originally developed by Trijicon. It quickly became the industry standard, and now the term is often used generically to describe any small, slide-mounted red dot on handgun. These sights project a reticle (usually a dot, but sometimes a circle-dot) onto a lens, allowing you to quickly acquire a target without needing to align traditional iron sights. There are two main types: open vs closed emitter. Open emitters have the LED exposed, while closed emitters have a protective shield. Closed emitters are more durable and can handle abuse, but some shooters prefer the cleaner sight picture of an open emitter.
MOA (Minute of Angle) refers to the size of the dot. A 3 MOA red dot subtends 1.5 inches at 50 yards, a 6 MOA red dot subtends 3 inches at 50 yards, and a 2 MOA red dot subtends 1 inch at 50 yards. For most pistol applications, 3 MOA vs 6 MOA for pistol use comes down to personal preference. A smaller dot (2-3 MOA) is more precise for longer-range shooting, while a larger dot (6 MOA) is faster to acquire in close quarters. Consider your primary use case when choosing. I generally recommend 3 MOA for concealed carry and general purpose, and 6 MOA for competition or defensive scenarios where speed is paramount.
The market is flooded with options. Here’s a breakdown of some of the most popular choices, categorized by price and features.
The Trijicon RMR is the gold standard. It’s incredibly durable and reliable. The RMR CC vs RMR difference lies primarily in the housing. The RMR CC (Compact) has a lower profile, making it more compatible with certain handguns and holsters. However, it has a shorter battery life (Trijicon RMR Type 2 Battery Life). Expect to pay around $500-$700 for a new RMR.
Crimson Trace offers a range of crimson trace 1550 review and other options, often at a more affordable price point. The Crimson Trace CTS-1500 vs 1550 comes down to size and features. The CTS-1500 is a more compact option, while the CTS-1550 offers a larger window and more adjustment options. They are known for their reliability and ease of use. Expect to pay $300-$500.
Holosun has quickly become a favorite among shooters due to its excellent value. They offer a wide range of options, including the HS507C (an RMR compatible red dot) and the HS403G. The Holosun competition red dot series is particularly popular for its features and affordability. Prices range from $150-$400.
Sig Sauer’s Romeo series, including the Romeo Zero Elite review and Romeo 3 Max footprint options, are also popular choices. The RomeoZero is a budget-friendly option, while the Romeo3 offers more features and a larger window. Sig Sauer also offers the Romeo Zero Elite which is a great value. Prices range from $200-$600.
Vortex offers reliable and affordable options like the Vortex Venom 6 MOA best price. They are known for their excellent customer service and lifetime warranty. Prices range from $200-$400.
The best red dot for Glock 19 isn’t necessarily the best red dot for Sig P365 XL. Here’s a breakdown by popular handgun models:
Proper mounting and zeroing are crucial. You’ll need a compatible slide plate and potentially a doctor cut optics mount if your handgun doesn’t come optics-ready. Once mounted, zeroing involves adjusting the sight to align with your point of impact. Use a red dot pistol zero target and follow the manufacturer’s instructions. How to zero in a red dot is a skill that takes practice, so be patient.
For those also considering an AR-15, red dot placement on AR is also important. Generally, a height over bore (HOB) of 1.5-2 inches is recommended for optimal co-witnessing with iron sights.
Co witness pistol red dot setups involve aligning the red dot reticle with your iron sights. This provides a backup sighting system if the red dot fails. Alternatively, best offset red dot setups allow for quick transitions between close-quarters and longer-range targets.
Absolutely. While there’s an initial investment, the benefits of a red dot on handgun – faster target acquisition, improved accuracy, and increased confidence – are well worth it. As technology improves and prices come down, red dots are becoming increasingly accessible to all shooters.
Remember to practice regularly with your new optic and consider taking a defensive pistol course to maximize your skills. Stay safe and shoot straight!
