Perfectly normal. Remove the loaded mag... Shake it.... It rattles the same.... In or out... It’s the same.
The mag is a double stack. The spring pressure on the ammunition inside the mag is different. It is not equal pressure on every round. The rattle is the noise you hear from a round of ammo moving into contact with the steel mag wall.
