I have the 9L pro series, and the 9L CORE pro series, and with a regular m&p 9 & had a G34. There is significant difference between between the standard m&p 9 trigger and both pro series guns. If it was not for the over travel adjustment on the CORE I would not be able to tell the two pro-series guns apart. The standard m&p 9 is on par with the G34 trigger. I pretty much only shoot the 9L CORE with a reflex sight now. the 9L pro series is just a back up and loner. Daughter shoots the standard m&p9
