Not sure, I haven't had a chance to handle one yet. Answer is probably yes. It's not anything wrong with the design - ZT explicitly describes them as an external stop pin.
unfortunately Jim Mcnair said in shot-show 0562 video i just sow
that they head complaints about the 0560 thumbstud was to difficult
so in the 0562 they completely made it a stop pin
which is a shame because 0560CF is even nicer looking then the 0561
btw, my 0200 is flipper & thumbstud and work grate,
after braking the 0200 flipper is working with no wrist movement.
and if your following the movement of the studs slowly
and not try make it fly of the handle (which is really dangerous) they're grate as well.
thank you for all the info,
but as you say with the 0561 the right handed studs are not doable
at all even after braking, thats an issue for me.
and i guess ill have to keep looking
or compromise on the 0560 or 0562CF which i really like.
