My SnG took about 600-800 open/close cycles to really smooth out. The unlock was especially sticky for a while, and Mick had to adjust the lock.
The main source of friction is the strength of the lockbar -- it pushes the detent ball against the bead-blasted blade, and makes it really stiff.
This of course makes for an incredibly strong lock and the tightest detent-closing power I've seen in a liner/framelock. For the initial retention (obviously not including the subsequent "pull") it rivals the Axis lock and some weaker lockbacks.
Guys, I hope you really enjoy her and give her a good workout. It's an incredible knife in many subtle ways.
