Don't ask them about a "trigger mod" or they will get all huffy with you and won't do a thing for you.However, if you complain that the trigger pull is gritty and 'catches' as you pull the trigger, they'll have you send it in and when it comes back to you it will be all slicked up.
One note, the newest ones have the pins "peened" in the sear assembly to make it very difficult to take it apart and clean up, probably a liability CYA by S&W.
For those low shooters, here is a shot of my 40VE with the Glock HiViz sight installed. Raises your POI about 2" at 25 yards.
