5. Trijicon RMRcc – Most Rugged

No products found.

The only reason I put this sight in the last position is that it comes with a hefty price tag.

The Trijicon RMRcc boasts the same durability as the popular RMR sight. It is Designed specifically for use with the single-stack Glock 43X MOS. There are two options if you want to mount the RMRcc on glock 43X.

  1. Milling the Non-MOS Glock 43X slide – One option is to have the slide of the non-MOS Glock 43X milled to accommodate the RMRcc. This involves removing material from the slide in a precise manner to create a mounting platform for the sight. This method may require the services of a gunsmith and can be a more expensive option.
  2. MOS Adapter Plate: Another option is to use a MOS adapter plate to mount the RMRcc to the Glock 43X MOS. This method is simpler and less expensive than milling the slide, as it involves mounting a pre-designed plate to the MOS system on the firearm. However, this option is only available for the MOS variant of the Glock 43X.

By choosing either of these methods, the Trijicon RMRcc can be successfully mounted onto the Glock 43X, providing an accurate and fast aiming solution that is particularly useful in self-defense or competitive shooting scenarios.

The Trijicon RMRcc is built with toughness and reliability in mind. Its construction is made from 7075 aluminum, which is known for its durability and strength, providing the sight with a sturdy and resilient build. The patented RMR square-top design is also incorporated in the RMRcc, ensuring that it is both shock-resistant and able to withstand heavy recoil from repeated firing.

Reason To Buy

The Trijicon RMRcc offers an exceptional combination of speed, accuracy, and durability, making it an excellent investment for anyone looking to improve their Glock 43X’s sighting capabilities.

Pros
  • Compact size and lightweight design
  • Durable construction
  • scratch-resistant lenses.
  • Adjustable LED brightness 
  • Clear and precise aiming 
  • 3.25 MOA dot reticle.
  • Long battery life 
  • Waterproof.
Cons
  • Relatively expensive compared
