[Milwaukee M18 drill chuck]

I love the Milwaukee M18 drill. It works awsome and just runs like a race horse. My biggest complain is the chuck, it sucks. My biggest issue is that it backs off for no reason. I saw on AVE that he replaced it with a keyed chuck but he didn't say where he got it. Does anyone know of a good replacement for this terrible chuck that they put on it?

[New to these lands.]

I'm new in these parts. I mostly use power tools for wood working and car repair. I used to be a big craftsman guy and recently switched to Milwaukee. I'm looking for some tips on these new devices.
