I was hoping to hear positive news about a new slide coming out of kt. A lot of people on this forum are convinced that kt resolved the peening slide issue. I don't believe it for a minute. You really shouldn't use the washer according to kt. I would shoot it and send it back if it peens. I have 200 rounds through my third slide and it is beginning to peen. I just use it for carry now and do not shoot it anymore. When kt gets the slides right, I will send mine back for replacement.
