Personally as a gunner fighting an MKT specificly (meaning I don't need to worry about someone hitting me with hacks... ect) I use the following.
Hat: Overdrive Bandana
Glasses: SSR Glasses
Overcoat: Elite Commando
Shirt: Squad Leader's (even though it has no thrown resistance, its damage/accuracy upgrades are unbeatable...)
Pants: Elite Commando
Gloves: Elite Commando (or GM Shinobi Gloves if you have them, I don't have them yet)
Shoes: Seraphim Shoes
You can use full Commando also and get good regain still but personally, OD bandana is the best for this kind of situation. You will not win against an MKT if it takes too long you need to do high damage and fast, if your a duelist and you get them dazed and/or offbalance go ahead and IL them... use firearms skill and despiration early you will need the extra damage and chance to hit if facing in IL.
Of course this gear/tactic is only my opinion, it's best to listen to as many opinions as you can and figure out something that works for you, something that should be there no matter what is some decent resistances. At least 150 or more...
Good luck.
