Thank you everyone for your thoughtful responses and letting me know this really isn't an issue, especially when racked properly
. The Shield owner's manual doesn't expressly go into detail about racking the slide fyi, so needless to say it doesn't mention out of battery problems. To clarify, I wasn't looking for permission to "ride the slide", I just didn't know if the gun staying out of battery on its own was bad news regardless, potentially being a danger to me. I did realize I made a mistake in my initial post: the gun won't stay out of battery with simply having the magazine in it, there does have to be at least 1 round in the magazine. This makes it hard to check at the store, unless they're willing to let you borrow a snap cap or something. Plus, with an empty magazine in the gun, you can't rack the slide because the stop catches it.
One additional comment about this gun: Don't let the manual safety deter anyone from getting this weapon. If you want to keep it off, it will NOT get in your way. It toggles very cleanly, with a nice crisp snap, and it is much easier to flip off than flip on. I hate to say this, but if you actually find a way to flip that safety on accidentally in the middle of a firefight, then it might just be your time to go cause it's not very likely. But I'm probably preaching to the choir when it comes to promoting this gun...
