A friend of mine had a P89 and it amazed me that a gun that could be purchased at that price could be that accurate and fun to shoot. I would bet that most of them are still running but have been replaced for lighter, less bulky options.
I saw a reminder the other day that if you are familiar with a Ruger P series pistol its time to have your prostate checked. It doesn't seem like its been that long since they come out until I did the math.
