Chuck/jaws spinning after releasing trigger on DCD791?

Hi all,

 

I've been looking at DeWalt's DCD791/DCF887 combo kit for a while and have tried it out at my nearest Lowe's, and noticed that when the trigger is released in second gear, the chuck and jaws continue to spin for a couple of seconds after releasing the trigger. Is this a common occurrence for the drill? My Makita subcompact doesn't do this and I noticed the Porter-Cable 18v brushless doesn't either. Was just curious what the purpose of it is and if it was the standard way it operates. Thanks!

It's just due to not being clamped and therefore loose enough to have momentum keep it spinning.

I recently got the DCD796 and it does this.

 

I've had a few bits fall out. It's like the chuck loosens due to the motor brake. I used it briefly yesterday and tightened the chuck a lot tighter than I usually do and the bits stayed in ok, although I feel the chuck was a tiny bit easier to loosen than I expected, so maybe it did loosen up a little bit but it's hard to tell.

 

Great drill!
