The mag can clearly be seen lieing there when the shooter enters the mosque for the first time.
When he returns from the large room, he picks it up.
So indeed, even though it didn't "spawn" – it can clearly be seen that it must have been there before he entered the buidling.
He had both hands on his gun when entering, so he couldn't have thrown it there.
