Most Helpful Positive Review Excellent Pistol Red Dot
I've got 3 of these now mounted on a Sig 5" X-Ten, an M&P 4" 10mm, and a PSA Dagger Full Size S (Glock 19x clone). All 3 have been very solid and have maintained zero even under the recoil of full power 10mm loads on both the Sig & M&P. The 507C-X2 uses an RMR footprint. I mounted them on the Sig X-Ten & the M&P 10mm using C&H Precision plates, and they are very securely mounted. I was used to using just a dot reticle with my RMR mounted on my M9A4. However, after trying the different reticle options on the 507C-X2, I've found that i really like utilizing the circle dot reticle. Which, for me,...

Exactly what I needed

by Completed, Verified Owner from AZ, United States Written on December 20, 2025
I purchased this for the Mossberg 590 OR. The gun came with the adapter plate to match this Holosun red dot without purchasing anything else. This is a shotgun so we will see how it holds up. It fit perfect torque to spec the screws and use proper thread locker. It was off zero by a couple clicks. I am thrilled how awesome this Holosun red dot compliments my use for this shotgun.

Holosun 507C-GR does not disappoint!

by Chris Slaubaugh, Verified Owner from AZ, United States Written on October 21, 2025
This is the first Holosun that I have purchased, primarily due to the cost. Optics Planet had it at a great price, so I took a chance. To say I am impressed would be an understatement! I went with the green dot, due to my astigmatism, and I cannot believe how clear the dot and circle are! The brightness adjustments are great. It looks and feels very sturdy compared to other brands I have looked at. It looks amazing on my gun (Smith & Wesson M&P 2.0 10mm) Overall, I am very happy with it and wish I would have gone with Holosun a long time ago!
Pros:
  • Price
  • Sturdy
  • Looks
  • great optics
  • solar capabilities
  • side battery tray
  • Adjustment capabilities
Cons:
  • None especially at price point
Best Used for:
  • A full sized pistol in almost all situations
