RE: 22 pistol
The single six by ruger hands down! The taurus full frame 8 shot ones are nice as are the S&W's.
I have a had a single six with the 22lr and 22mag cylinders. Excelent gun. I had a browning buckmark automatic that was great too.
This is deffinately not the gun you want for quiet cat control in your other post. They are louder than all get out! You might as well get a 12 gauge if you are going to use a .22 revolver. As far as noise is concerned any way.
