Just to add a little: right after I got my permit recently, I rented an SP101 at our local range, test-fired it and was quite happy. Went back and the next time I wrote down its serial number. Checked the Ruger website and found out it was over eleven years old (!), was working as tigh as ever, and had very good groups at 25 feet. Eleven years being used as a rental is phenomenal, in my opinion. But not too surprising for a Ruger; my Mark 1 target pistol has over 10,000 rounds in it and is still going strong.
