Well... I know the judge in many discussions has already been convicted and sentenced to being worthless. However, it is our bedstand gun.
When I first saw one, I was of two minds about it myself, read a few posts and then decided to not waffle back and forth on others opinions and get one and form an opinion from personal experience. My LGS is a good guy and I shared my concerns with him before the purchase and we agreed on a fair return in value should I not be happy. I then bought a pack of 45 and a box of Win PDX1 for it.
My wife and I shot a few rounds to get the feel for it. We both thought it was a nice gun. I'm not going to get into super specifics as to exact accuracy, as I've never tested it for anything other than rough grouping at 20' (It's intended use for us was to be as a bedroom protection middle of the night thing.)
Set up a roughly 3x5 3/4" plywood target with an old heavy quilt on it and then had my wife stand about 20' away and practice picking the gun up from a table and bringing it into alignment with the board. I did the same. Once we got fairly consistent, I had her keep her eyes closed and repeat the same maneuver. The thought here was that it would likely be dark or nearly low light, or backlit if someone made it to the bedroom. I wanted to see how well she (and I) could point with it in the dark.
All I can say is that when either of us shot the target - I would not want to be standing there. My wife's first shot was a little low - and the biggest batch of holes would mean at the very least, a male intruder likely wouldn't be passing on anymore genetic material to another generation. I shot high (guess it makes sense, I set the target center of mass up about 5 1/2' high, and I'm a good foot taller than my wife) Either way. I was more than satisfied that it would do the job. I was happy with the performance of the ammo, and my wife and I both felt competent enough with the Judge. What more can one ask.
*edit* While ours was purchased as a home defense gun, that is what I ever only saw it as, or as a close in varmint eradicator. I consider it to be well designed for that task. Thought it might also work great clearing out pigeons or rats in a barn setting. Never considered it as a carry weapon. I agree that there are better tools for that job.
