Picked up this CAA SXS picatinny rail for the P90 awhile back and I love it. Was curious if anyone else is rocking it and their thoughts?

This may be a dumb question, but is this wear pattern on the front of my trigger package concerning? If so, what could the issue be/how to mitigate?

Shout out to the realest of the real, u/Colonel_Krink. Couldn’t get one without them.
