I have a standard Browning Buckmark (circa 1999) and a recently purchased Ruger Mark III 22/45 Hunter. I just took the Ruger to the range this morning. I shoot the Buckmark better than the Ruger, but both are fine target and plinking .22's. They both feel very similar with the Browning having a lighter trigger. I did remove the magazine disconnect safety on the Ruger and that improved disassembly, magazine drop, and the trigger feel. The Buckmark is still box stock.
You wouldn't go wrong with either of these pistols so how they feel in your hand may be the deciding factor.... unless you can rent one and check it out.
