I recently bought a used one from a local firearms instructor, it was his personal gun. I am sure it has a lot of rounds through it. But I also know it is broken in. Haven't had it long, so only been to the range once. Ran 100 rounds through it absoluely no problems. My son has had a full size for several years and he has had no problems. He and some buddies were out on our farm and ran into a 250 lb. hog. He killed with his 9mm. Not recomending hog hunting with a 9, but it worked for him.
