Adjusting Mag release on new Shadow II

[Sigint2651]

I just got a new urban gray Shadow II,  and it claims that the magazine release has three adjustments to it.

There is really nothing in the manual to tell me anything about how this is done. 

I tried unscrewing the mag release screw and it will not budge, and even if I can get it loose, exactly how do I adjust the mag release?
 It sticks farther out than I want it to, and I would like to set it closer to the gun frame.  I emailed CZ three days ago and they have
not bothered to reply. 

Can anyone tell me what I need to do to accomplish this?  I don't want to twist the head off the mag release screw or anything like that.

   The only adjustability in the Shadow 2 Magazine Release is the rotational position. The button depth is not adjustable. For this you can swap out the Mag Release to a shorter one.

   The screw that holds the Mag Release button in place is likely thread locked. To take this screw out without stripping it, heat is advised. I used a soldering iron to heat mine up last time i removed one and it came out without issue.
