G22 full mag rattles

[patriotpower]

Just traded into a Glock 22. Chambered a round, inserted full mag. Something is rattling in the mag. Any tips?

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.
