In this guide, let's take a look at the best red dot sights for Ruger GP100  revolvers. We will also include links to buy compatible red dot mount plates and top rail adapter.

The full length railed adapter is the easiest for optic mounting.

Let's check them out...

Trijicon RMR fiber optic


Why everyone goes for the RMR - The Trijicon RMR is the gold standard for micro pistol reflex sights. This optic can survive much more recoil even on a 50 CAL Desert Eagle. Recommend mounting this on a railed Ruger GP100 with a picatinny mount.

What are people saying about the TYPE 2 model - The RMR Type 2 is basically the same as the original model, but it's specifically built to handle handgun slide high speed G force that means it can handle a 357 revolver

The newly added feature, the battery compartment now has a better grip on the battery to prevent it from getting loose causing the dot to go out.

The optic is lightweight and has robust mounting points to go on the 44 Magnum.

3 MOA sizes - The 3.25 MOA model has the best dot size that is easy to pick up to shooting.

holosun 507c x2 front lens


Why this is a better option than Trijicon RMR - The Holosun 507C is the best Trijicon RMR alternativ  because it's affordable and has the same durability. Recommend mounting this on a railed Ruger GP100 with a picatinny mount.

Different design and it works flawlessly on various handgun platforms. it offers:

  • 2 MOA dot 
  • 32 MOA ring
  • 32 MOA ring only

Near Infinite Battery life - The Shake Awake technology & solar panel extends the battery life way past 50,000 hours. Motion sensor activates & deactivates the reticle for battery saving, and the Solar fail-safe power kicks in immediately when the battery dies, so the optic will always remain on.

Cost Effective - One thing people love about the Holosun 507C is it's much cheaper than an RMR and it does the same thing, and it shares the same mounting footprint, so if you don't have to buy a special mount for every time you want to swap optic.

At this price point, this optic almost surpasses the Trijicon RMR, and you'll save a ton of money. Just make sure to click the button below for the best deal.
