m&p40 apex trigger help. in Firearm Hobby / Sport Discussion Posted March 20, 2015 I had an M&P FSS trigger kit, installed by a certified armorer, and it did not have an audible reset. From reading, I agree to hear the "noise" you might need the RAM. Yeah I called them. They told me it is normal. To get the audible reset I need the ram kit. my m&p has the internal locking system so I would need to remove that in order to be able to use the ram kit. Gotta look into how to do it.
