I love the idea of a red dot but my eyes don't see a round dot unless I put glasses on :cry: ,had thought about 1 for my mark11 target pistol but hate wearing my glasses,tried 1 on my pellet rifle and at 35y the accuracy wasn't there compared to a regular scope,now self defense close up I don't think it can be beat unless very bright lighting effects it,would love to try different set ups before I spend big $ on some thing that might not work for me personally
