Holster/accessories for Malkoff MD2

I’ve been looking at buying a good flashlight that uses rechargeable batteries, I’ve been looking at them for a couple of years now, as I use a flashlight quite often at work. I think I have settled on a Malkoff MD2. My main reason for starting this thread, is to ask any of you that have a MD2, what’s a good, tough, holds-up-to abuse holster, that will work? We got flashlights from our supervisor a year ago, and the holster broke on the second day, I want something bulletproof, or close to it.

I work at a Cement Plant, so I want a light that will hold up to the worst kind of dust imaginable, occasional water(from rain), and abuse, will this MD2 fit that bill? Also, I’m getting a grasp on some of this battery/charger stuff, but am still a bit of a NOOB, I’m going to stick with the same Keeppower 3500ah 18650 protected batteries, that are sold on Malkoffs website, and am going with a Miboxer charger(either the c4-12 or the c4plus), any recommendations on which charger, or why I should go with something else on batteries or chargers, will be much appreciated.

Thanks in advance.
