I noticed my P9 beginning to occasionally fire rounds almost by itself;almost before I exerted any pressure on the trigger. I e-mailed Kahr and advised them of the situation. Told me to immediately send pistol to them (used UPS 2nd Day Air). I returned it on August 18 and had it returned to me by them via FedEx on August 26. Haven't had an opportunity to test fire it, although I could tell Kahr had done this. I was very impressed with how serious they took the random malfunctioning to be, and how quickly they repaired and returned the P9 to me.
