I am a fan of the M&P with multiple 1.0s and 2.0s. I recently purchased a S&W M&P CORE 5 inch "top end" for a M&P 1.0 frame. I am concerned about the CORE loaded chamber indicator "notches" in barrel and slide putting debris etc. on my RDS. Has anyone tried to "fill in" the LCI notches or anything else to prevent this issue? Any experiences?
I have not shot the CORE upper yet as I am debating selling it due to the LCI concern and just getting another CZ P10F/C OR.
