Timney 2 stage doesn't work with JP safety

[ropsitos]

So I went to install a JP safety (which I have on every other rifle I have) with a Timney two stage trigger I had one off a prize table.  Thought I would use it on a precision ar15 6.5 Grendel build.  The trigger worked fine with a std safety (static checks; never fired).

 

with the JP safety in the fire position, the hammer wouldn't release.  I measured the notch on the selector barrel when in fire position and it was about .088" deep where the std one was about .112" or so.  It looked like the travel of the two stage needs the space afforded by the deeper notch.

 

wondering if anyone has had a similar experience, and if anyone thinks it's worth deepening the notch in the JP.  I love how the set screw in the JP solidifies the feel of the trigger when it's on safe.  Just not sure if it's worth it vs just getting another brand of ambi safety
