Ruger Mark II/III or Buckmark.
Between the two, I prefer the Ruger, but the Browning is nice too.
If you get a Ruger, get a Volquartsen sear and trigger - brings the trigger pull down to about 2-lbs with a nice crisp break.
I'd recommend avoiding the Ruger Mk3 22/45. There are a large number of people (including myself) having serious FTF/FTE problems with that gun. There are fixes for the problems out there, but they are coming from the gun owner community, not Ruger.
I had these problems out of the box with my MKIII as well. Its an extractor issue.
The factory Ruger extractor does not hold the brass tight to the bolt face. Thus the brass is not presented to the ejector properly, causing all too frequent jams of various descriptions.
Buy a Volquartsen "exact edge" extractor. Its a $12 part that takes 5 minutes to install. It cleared up all of my problems: my MKIII has been 100% reliable in the 500+ rounds I have fired since installation. Before that it jammed regularly at 30 to 40 round intervals. Now I can fire the same ammunition and mags all day with no problems. Accuracy still is and always was very good.
