EE, that's what I had to be "induced" to do. When I bought mine, I triple-checked the chamber, pointed it at the floor then dry-fired it...right before the dealer reached across the counter and showed me the multiple warnings in the manual *not* to dry-fire it...(0.75 seconds after I had already done it).
Gulp (embarrassment)...OK, on new gun designs I'm not familiar with, I'm going to read the f'er FIRST from now on, lesson learned.
(The one slip-up doesn't seem to have hurt the functioning, though).
