So I signed up for my first classifier match this weekend. I’ve gone through the rules so I think I have my class right which I think is limited since I will be shooting my duty gun (S&W M&P .40 long slide) which has grip tape and a gun light which I think qualifies for production but I run my mags forward of my hip which puts me in the limited class. I hope I have that right? And since it’s a .40 shooting factory 180 grain loads it should be major? So it’s a 4 stage classifier but I’m not sure of the round count any idea how much I should bring? I will be running an als/sls holster with a leg strap for stability (it’s not a drop leg) which I think is legal. Eventually I would like to set up a dedicated belt for this but I happened to have a day off that lined up with this match. Also if I change guns after this match will that effect any future matches? (assuming I don’t dq myself and qualify) I want to pick up an M&P 2.0 5” in 9mm once the one without the safety and lci becomes available. Any tips or things not to do?
