They have the best release in the business, why on earth would they change it??? Much faster than "normal" release... just use your trigger finger. No need to change your grip.
Meh, I gotta contend with this one.
While I'm sure enough practice would change the full disparity in "speed", from a natural "blank slate" stand point, your claim doesn't hold true for everyone. For example, I don't have to change my grip much at all on my EDC-- drop the strong thumb (which doesn't contact the pistol anyway) and out she goes. I have a difficult time on every HK I've ever tried, although it's admittedly easier with the full sized frames than with the compacts.
But to be fair, I might very well be the rarity in this regard. Just the same, it's not a sweeping truth. And I don't think with any amount of practice would I ever be as quick with an HK as I would be with any thumb-activated release-- especially not my M&P.
In reality, even with full competition rigs in place, dropping the mag and reacquiring a shooting grip (with the strong hand) is NOT the slow part of the process. Getting the mag off of your belt and into the gun, re-establishing your support hand position and getting the sights back on target are the all vastly more time consuming-- and problematic. Don't believe me? Watch Travis!
It's even more pronounced for we mere mortals, of course. Now I'm not saying that the mag drop CAN'T be the cause of a slow reload-- I've had it happen myself several times, thanks to ProGrip... But it's not the be-all, end-all of the process.
