Detailed Comparison
RMRcc
The RMRcc, produced by Trijicon, is a refinement of their previous models, compact and specifically designed for concealed carry. I’ve found that one of the top features of the RMRcc is its durability. Built with a forged aluminum housing, it’s designed to withstand harsh elements and hard recoil.
In terms of functionality, the RMRcc has an automatic brightness mode, but also allows for manual brightness adjustments as per your shooting environment. It is parallax-free, meaning the aiming point remains consistent, even if your viewpoint shifts.
One challenge with the RMRcc is the battery mounting system. It requires the sight’s de-installation to replace the battery – not the easiest process as one might imagine. Despite that, it is balanced out by the device’s impressive battery life of up to four years.
Pros of RMRcc:
- Highly durable with a forged aluminum housing
- Automatic brightness mode
- Compact design suitable for concealed carry pistols
- Long battery life
Cons of RMRcc:
- Battery needs sight to be removed to replace
- Price is on the higher side compared to Holosun 507k
Holosun 507k
The Holosun 507k, on the other hand, is recognized for its advanced technology and versatility. What I particularly enjoy is its multi-reticle system, which allows users to switch between a 2 MOA Dot, a 32 MOA Circle, and a circle-dot combo. Such versatility enhances its adaptability to various shooting conditions.
One distinct feature of the Holosun 507k is the ‘Shake Awake’ technology. This feature cleverly puts the device in sleep mode when it sits idle for a certain period, thereby saving battery. Once moved, the optic instantly powers on to the last known setting.
On the downside, the Holosun 507k’s buttons are somewhat sensitive, leading to unintentional settings adjustments. However, its multi-layer coating lenses, improved visual clarity, and longer battery life, serve as a worthy counterbalance.
Pros of Holosun 507k:
- Multiple reticle options
- Advanced ‘Shake Awake’ technology for battery conservation
- Longer battery life compared to RMRcc
- More affordable price compared to RMRcc
Cons of Holosun 507k:
- Sensitive adjustment buttons can lead to unintended settings changes
- Heavier than the RMRcc
Both the RMRcc and Holosun 507k have commendable features that enhance shooting precision. Your decision between the two should be based on personal usability and preferences taking into account factors like price, durability, battery life and technical features.
