I have a standard 9mm FS M&P.

I plan to install an Apex DCAEK and Trijicon Aftermarket sights soon. I also ordered an Apex Polymer trigger.

Since I have an interest in starting up in local competitive shooting as a relaxing hobby, last night, I spent some time reading through several on-line rule books (idpa, maybe?).

Anyway, the takeaway I had was:

Apex DCAEK - parts not visible, ok to use
Trijicon Sights - Aftermarket sight, ok to use
Apex poly trigger - Visible modification, would not be allowed.

Is this about the right rule-book interpretation, 'in general'?

Would I be losing a whole lot if I returned the Apex Poly trigger back to Midway for a refund?

Thanks in advance.
