OpticsPlanet accidentally sent me an RM01 with a 3.25 moa dot. It was kind of lucky since I got to see the difference between the 3.25 and the 8 moa dot. The 8 moa is way better for pistol shooting - it's faster on target and much easier to see. Go with the 8 moa for pistol or other close range applications.
Pros: Size, durability
