They are way nicer to see that is for sure. The first 22A that I bought did not have the HiViz sight on it. I had a chance at the range one day to use one that did have it. Well the rest is history, I sold the first one I bought and went out and bought the fancy model with the HiViz sight on it.
I might add that I have had almost ever .22 auto handgun there is and for the money it is hard to beat these guns, in my opinion.
