@@ScotchNThings Not sure if this applies to the LUDT, but for what it's worth, the same issue was raised by a ProTech auto user. The reply he got was that it was a safety feature, not a defect. It prevents the blade from firing unless the button is fully engaged.
mark case ya it gotten better with time. The socom is on my short list as soon as I can find a color I like. I kind of want to get blue to match my LUDT
Looks great in blue! Also picked up mine from GPKnives, they were great. I also had some button stick. Lubed with some nano oil and eventually went away with use. Do you still have the issue after a few months?
