This sightmark would not hold zero, just when i thought i had it, it would move. it was about half the price of the holosun, but still should hold zero. i have other ones on AR's and they work fine..but they don;t get jolted foward and back like on a pistol. the Taurus Tactical has an aggressive grip like the smith 10mm i do not like.
It's not quite as aggressive as the smith but after several rounds you can fell it. it also has the recoil of a 10mm. also forgot me magic marker is why the sicks are in the holes. lol
