I had around 50 disarming kits at me ...
And almost every vendor is selling few more. :-/
So i dont quite see the reason. O_o
If you dont want to drag them all by you, bcs they have some (negligible) weight, you can have them in your camp and take just few with you.
I still dont understand why cant we change Race for our hirelings.

Lets us play Githyanki as racist as they trully are!
