Its especially dangerous since it appears to me that its an unloaded weapon. Looks like the magazine has been removed.
Jes sayin’......it is possible that a live round may remain in the chamber when the magazine has been removed [or inserted, for that matter]
We were taught....**Never leave a firearm unattended, whether loaded or unloaded. Always put a responsible and competent adult in charge of your firearm to maintain safety and reduce the likelihood of accidents.**
