I just picked up one myself and have been looking at optics. I think I am going to go with some sort of red dot since this will be a short range gun for me as well. My other decission is how to mount it. I would love to mount it a little higher to make it easier to aquire a target with out haveing to put my cheek all the way down to the stock but if I do mount high it will block the fixed sights. Or I could do a lower mout and get a co-witness out of it but those stock sights are so big and bulky. Wish they would have made those removeable so you put a flip up on it.
