Ok I shot my second USPSA match today, which also concluded my "dirty EMP" test. I'm actually not sure if I should clean it or continue doing the test. I'm leaning more towards cleaning it, primarily because it is my CCW gun. I don't believe this gun will malfunction, but it's been dirty for a few months now! You can see my original threads here: http://www.glocktalk.com/forums/showthread.php?t=1349649&highlight=harrison+EMP http://www.glocktalk.com/forums/showthread.php?t=1353729&highlight=harrison+EMP I have a total of ~2,100 rounds through it, ~1,600 since it's been refinished, and ~1,100 the gun has not been cleaned, except the barrel. When my rear sight came loose, I wanted a clean barrel to ensure accuracy (just in case). Other than that, nothing has been touched. I re-lubed it with Hoppes #9 whenever I felt the need, usually every couple hundred rounds. I can say with 100% truth that the only failure I've had was 2 FTE in the first magazine. Other than that, the gun literally has had ZERO malfunctions. I chose John because of his philosophy, "The gun has to run." Some people have responded and ask why I did this, or why other people do it. I can't vouch for them, but for me it's a test of endurance and equipment failure. If something is going to jam, break, or malfunction, it's most likely going to be when it's dirty. My philosophy is if the gun will run with debris and gunk in it, it will run when it's clean. Now my pictures certainly are not the best. I was in a hurry and the room is a bit dark. Click for high res.
