No, the slide doesn't lock back after the last round.
how to load bbs
You load 12 BB's at a time. Pull down & lock the follower an and then push the lever thing at the top of the mag and pop BB's into the magazine while making sure the spring follower doesn't come free and blast the BB's out the top of the magazine.
Might be difficult for kids and women, but should be OK for teenage boys. Just remember to not point the barrel downward while cocking, or the bb might fall out.
