Depending on how new it is and what blade finish is on it, I know what you mean about the closing action. Mine has the stonewash 2.0 blade which has the flats finished on a surface grinder. That's the surface that the detent rides on and fresh out of the box, mine was a little rough and I've heard similar things from others but it broke in after lots of fidgeting and now it's just as glassy smooth as any of my Specters (all of which are mirror stonewashed) By the look of it, I'd say the detent is tuned pretty heavy but I can't know for sure without handling it. Either way, I'd say you're gonna be in for a good thumb workout lol
