This rugged piece of technology has been through the wringer – it can survive the recoil of even a Desert Eagle and is built to handle the high-speed G force of a handgun slide, which means it’s more than ready for your 357 revolvers. 

The Trijicon RMR Type 2 model has a new and improved battery compartment with a better grip on the battery. This means you won’t have to worry about the dot going out because the batteries come loose. 

It’s lightweight and robust, ready to be mounted on anything, even a 44 Magnum! The best part? The 3.25 MOA model has a dot size that’s perfect for shooting – easy to pick up and won’t leave you squinting.

The Vortex Venom is a shooter’s favorite. For under $250, you get a compact reflex red dot sight built with rugged aluminum housing. 

But don’t let its lightweight (1.1 oz!) fool you – it’s sturdy as can be. It feels like a featherweight on the Ruger GP100, and the synergy between them is nothing short of impressive.

One feature that stands out with the Vortex Venom is the top-loading battery access. This means no sight removal for battery swaps or re-zeroing – a convenience that echoes the user-friendly design of the Holosun 507C. 

The Venom’s lens is clear, bright, and sealed with an O-ring to keep moisture, dirt, and debris at bay. This sight is shock, water, and fog proof, ticking all the right boxes for a solid sight. And the size of the red dot? A perfect 3 MOA.

Holosun has delivered a real game-changer with the HS507C X2. It’s cost-effective, offering similar features and durability as an RMR but at a fraction of the price. And it’s not just the price tag that will make you smile.

The mounting footprint is identical to the RMR, saving you the hassle of finding a special mount every time you want to switch optics.

The HS507C X2 offers three reticle options – a 2 MOA dot, a 32 MOA ring, or just the 32 MOA ring. The standout feature has to be the Shake Awake technology coupled with the solar panel. 

It’s designed to extend battery life past 50,000 hours by activating and deactivating the reticle based on movement. And if the battery dies, the Solar fail-safe power kicks in immediately to keep your optic on. 

It uses a CR1632 battery which is conveniently accessible from a side tray, negating the need for sight removal when swapping batteries.

My Experience

Putting the Holosun HS507C X2 to the test with the Ruger GP100 was a breeze. It’s sturdy, with a matte black anodized finish that screams premium quality. 

The lens is multi-coated, providing an impressively bright sight image, even in harsh weather.


Affordable and durable

  • Three reticle options for versatility
  • Extended battery life with Shake Awake technology and Solar fail-safe power
  • Easy battery access without removing the sight
  • Fog, shock, and waterproof

There are two optic plates that stand out, one from Allchin Gun Parts and the other from Weigand Machine and Design.

The Allchin Gun Parts offers a micro red dot mount plate that’s drilled with various holes, which means it can accommodate different types of optics. This is a plus for those who may want to switch between optics. It’s also easy to install, making it a convenient choice.

On the other hand, Weigand Machine and Design provide a long Picatinny rail, which is compatible with most optics that use an M1913 mount. 

This can be particularly advantageous for those who prefer a standardized mounting solution. What’s even more impressive is that it does not require any drilling for installation, which is a huge plus.

Can you put a scope on a Ruger GP100?

Yes, you can mount a scope on a Ruger GP100. However, you will need a scope mount or rail adapter. Make sure to choose one that is compatible with the GP100’s mounting points.

Is a Ruger GP100 worth it?

Absolutely. The Ruger GP100 is renowned for its robustness, reliability, and accuracy. It’s a great choice for both target shooting and hunting, especially with its .357 Magnum caliber. Its excellent reputation and performance make it worth the investment for many gun enthusiasts.

Which is better, Ruger GP100 or SP101?

Both the Ruger GP100 and SP101 are solid revolvers, but the choice depends on your needs. The GP100 is larger and heavier, making it more suitable for home defense or hunting. It handles recoil better due to its size and weight. On the other hand, the SP101 is more compact and lighter, making it an excellent choice for concealed carry.

Is Ruger GP100 good for concealed carry?

While the Ruger GP100 is a fantastic revolver, its size and weight might make it a bit challenging for everyday concealed carry. It’s larger and heavier than many options designed specifically for concealed carry, like the Ruger SP101. That said, it could work for concealed carry if you prefer larger revolvers and have an appropriate holster and clothing.
