Hello Katsu, Tok is correct, and thanks for providing the link Tok..
Also, if it makes a difference to you, the Stainless 75B ( later one with big beaver tail) come with a lower profile, tumbler type ambi safety, which seems to be identical to the 85C except it is in stainless. Not cheap either.
They aren't super low profile, but they won't create an issue for holstering like the paddle type may.
When I get some free time, I am going to make a block off for the right side ( I know someone here did that already).
Good Luck!!
