I used the scope for the first time at an indoor range last night on my Ruger Mark III 22 pistol. Works great. Shot 200 rounds nearly all within 3 inch ring. This this is huge for me. Tried out the red and green on each size dot the fine dot was the best for 25 yard shooting for me. You can't miss with this scope. Worked great for both eyes open aiming which I was never able to get with the focus on the front sight method. Super fast target following shot target acquisition. I was able to be back on target faster than I could pull the trigger because of range rule shot timing of 1 second between rounds. So it is great for target work but I can't see using on my concealed carry gun. Not very concealable, so I better not become dependant on it. But for target and hunting it would be an awesome buy for the money.
