I just did the same thing with my 22A. Ended up with a Simmons 2x6, and so far it's great. The main draw for me was that my gun shop had it and i can fix some of the parallax with the magnification adjustment. I looked at some straight power scopes, and the reticle wiggled all over the place at 25yds. My account for this was that most handgun scopes are for revolvers and hunting. I think most scope manufacturers set the parallax at 100yds. (Anyone feel free to correct me if i'm wrong.)
It's fun and much more accurate now. At 25yds i can easily shoot 1" groups. Hope this helps.
