I had one for about 10 years and put a lot of rounds through it. However, twice, during two different handgun classes, the take down lever(?) backed out just enough to disengage the trigger. Two times in the a 1,000 rounds is a lot even if there were 9000 trouble free rounds. I decided I couldn't rely on it any longer. I understood the sense of urgency as both times I was in the middle of firing and moving. I had to keep moving and diagnosing on the run. I recognized it right away the second time just by how the trigger felt. The asst. instructor wanted me to slap, rack, and roll but I ignored him so I could fix the problem. I believe I had about 10k rounds through the pistol. I sold it for not much less then I paid new and counted it good. I don't know if I was inadvertently pushing on the backside of the lever or what. Ruger said I could buy a new lever to see if that was the problem. Selling was cheaper and less stressful.
