Questions & Answers
I purchased sightmark sm26043 . Taurus tx22 COMPTITION. Two screws required are NOT IN KIT. The forward screws are different pitch&size. Expert Answer

The Taurus TX22 Competition mount is made to be nearly universal. Unfortunately, we do not carry alternative mounting screws.

What is the actual slide cut footprint of this optic? If I have a slide that is milled to fit a Trijicon RMR or Holosun 507c...will this work as well? Expert Answer

This optic follows the Docter/Burris mounting pattern. It will not fit an RMR drilled slide without an adapter.

Sightmark Mini Shot by Slugger, October 24, 2022
This is the second such sight I've bought. I've mounted them on shotguns. They can withstand the heavy recoil that results from shooting slugs in my guns. They are also very low profile, with the red dot only slightly higher than the sighting plan...

good addition to handgun by hunteruser7, July 27, 2021
I used this on a handgun which was a nice addition. While having my arms locked out in front, this M-Spec was the perfect missing piece I needed. It helped me to aim properly and keep my eye on the target.
