I want just upgrade the hinged trigger on my
m&p 1.0 Performance Center C.O.R.E. 40L
with the APEX poly action kit..
Just the trigger and sear spring..

Now my question.. Since my 40L has the adjustable trigger stop, can I still use the poly 1 piece non hinged APEX trigger?

or do I need to remove the overstop screw from frame.

Hope this makes sense.. i don't need to change the sear and plunger as they are already perfect from the Performance Center shop..

Thanks in advance.

I have the poly trigger on two of my M&Ps, and it is straighter (less curve) than the factory hinged trigger. Because of the different shape, I'm not sure the adjustable trigger stop will work.
But the hinged trigger straightens as it's pulled.

You'll just have to try the stop after you install the trigger.
This is the Apex poly trigger on my MP9 on top, compared to the other two having hinged triggers:
