    I haven’t loaded them to the max, but they tend to rattle and I’ve notice when I was loading them last week. Anything can be done about this?

    It's normal when not fully loaded.

    Hey, how exactly is a rainbow made?
    How exactly does the sun set?
    How exactly does the posi-trac rear end on a Plymouth work!?

    It just does.

    It may gradually go away as spring settles, but it’s not an issue.

    If you look at a clear magazine you will see at the top why the “rattle” occurs. The double stack to single feed design causes the rounds to get in kind of wonky position, and your hearing that one rounds top portion being able to move around.

    Looks scary but it’s normal.

    ...and things shift around as the mag feeds. So the rattles can move and be intermittent.

    I asked this once here. It was recommended that I tap the magazines with a good amount of force on my head, multiple times. It worked.

    I take my thumb and press down on the top round of a loaded mag a couple or three times to make sure all rounds a tight and feed properly. It also tests the tension of the mag spring operation to see if it is working properly.

    Some do, some don't. Have had several that rattle when fully loaded. Have had some that didn't rattle until seated in grip. Who knows??? All I do if I have one that rattles is remove one round and it's good.

    Jamaal as noted above it seems fairly normal, I noticed this on Glock 19 magazines in the late 80s/early 90s BTW..

    I thought the rattle was a pretty standard feature. It is right up there with the "screen door creak" sound my G17 makes when moving the slide.

    Sort've like malamutes, beagles, and basset hounds... they are bit more vocal than other breeds!

    I can smack most of my mags to get them to stop clacking, but I have some mags that apparently have some rattlesnake DNA in their blood. It is more amusing than annoying for me.

    Tapping only works with 9mm magazines. The .45 ACP double-stack magazines will continue to rattle. The rounds rattle for several reasons. The top rattle is one thing, but they can also rattle in the middle of the stack.

    Imagine a sequence of rounds, in a true double stack magazine, away from the top or bottom: #1, 2, 3, 4, 5. And let's say #3 is juuuuust a little smaller than the rest of them. The pressure from the bottom will get trasferred through the even column around the round #3, letting it slide back and forth and rattle. One can actually see it through witness holes.

    This will continue to happen no matter the tapping. However, the 9mm rounds are not actually straight wall, so a good tap lets the stacks adjust and form a little zig-zag that prevents the longitudinal movement. No such luck with .45 and its straight wall.

    Rounds don't lay perfectly snug against each other...they will rattle.

    You can try to get them to snuggle up by pounding the mag against a surface, or smashing down on them from the top, but once they move they may rattle again.

    Same reason a rattlesnake rattles. Because they’re deadly.

    If you hear the rattle when the weapon fires, there is a problem. Other than that, normal.

    There really are answers to those questions.
    Rainbow: full spectrum light travels through a raindrop which acts as a prism and splits the light into based on wavelength. It does this in a ring but the ground cuts the bottom half and it looks like a bow. Scene from the air ( as in a plane) a rainbow’s full ring can be seen.

    Sun set: earth rotates

    Posi: probably a limited slip dif.

    Most of mine will do this. I just wack the base of the mag on my hand and it stops. Sometimes you only have to wack once, sometimes a couple of times. I do this when I load them and they don’t rattle anymore. Not sure if they will rattle without being loaded all the way. I usually only have a fully loaded mag or an empty mag lol.
