I wouldnt worry about it..especially if its a carry piece.
When i was new to handguns. I re assembled my p220 and forgot to put the takedown lever in the locked position. I then proceeded to hit the slide release, throwing my slide downrange onto the concrete.
****ups happen.
I did this with one of my Sigs way back when just to see how far the slide would launch...
