I have a new PM2 in brown G10, S35VN, DLC, black hardware. I like it and have had it for about a month maybe. I have had issues with a PM2 before that really turned me off of the knife. It was mostly related to blade play. So, I periodically test for play very lightly. Well, up until a day or two ago (the last time I tested it) it had no play. I test it tonight and sure enough, there’s vertical play. I have rotated the stop pin, tightened the screws, etc. It’s not lock related as I feel no flex or movement on the lock when testing for play. It’s not a lot of play but it’s certainly noticeable when checking for it. Am I being too picky? I’m really bummed out. This is the second one I’ve had and the second issue I’ve had with play. Should I send it in for warranty work or just get over it? Thanks guys.
