My Shield does this also but so does my Glock 27 and most of my other striker fired firearms. Careful holstering makes this a non-issue. I have drawn and holstered from a DeSantis Speed Scabbard made for a M&P9c with no problems whatsoever.
That's BS on the Glock 27 doing it, sure it might push back if you don't put you thumb on it as you reholster, but it goes back into battery on it's own. I've been carrying the 26 and 27 in pocket holsters and many other type holsters for many years. This never happened, not even with a new gun.
