Bout 200 rounds through my G21 and I noticed a noise when I picked it up. I shook it and heard a rattle, a little investigating revealed the rattle is coming from the slide. I can grab the front of the slide and move it side to side bit, not alot but I can move and if I shake the thing it rattles. This normal?

If the rattle goes away when there is a round in the chamber, it is normal. Sometimes referred to as the "Glock Rattle".

 

[SHOOTER13]

Yup...not to worry !!

 

[Burnsy]

ok, yeah the sound does still happen and I can still move the slide with one in the tube but if a mod tells me not to worry I shall not....but I gotta ask...why? Should it not fit tight?

Too tight a fit can make a reliable gun unreliable...

Ahh, makes sense, thanks Shooter!

Thanks for reposting the vid, Mike, I was gonna try and look for it.

Cheers to all!

Ok nother noob question as I was thinking about this, If the slide tolarance is loose to add reliability that's great, but would the sights not move side to side along with the slide? Meaning the slide starts out in the middle perfectly alignted then let one fly. Could the slide not now be 1/16 or something to right and therefore my sights are 1/16th to the right? Please do not mis-understand me, that small difference would make NO difference to me, I get happy when I plug one anywhere need the center at the moment.

 

[Happysniper1]

Well, look at it this way:

The barrel is locked into the slide at the moment of firing.

The slide does not begin to move back until nanoseconds after the bullet has exited the muzzle.

And, yeah, I used to wonder about that years ago, too.

Cheers!

It's not the slide that is loose. It's the firing pin that's in the firing pin channel, that's in the slide.

Here's a so-so quality video that illustrates what I mentioned above:

No it's the slide that moves, I can move it side to side a small distance C1 or empty.

Ok that makes sense, I think, thanks.

 

[Happysniper1]

Yep, and since the barrel is locked into the slide, it is aligned with the sights, even if the slide has some side-to-side play against the frame.

Hope that helps.

Cheers!

Yes, but are you sure that's what's making the noise? The noise/rattle that is being described above is your striker moving in the channel.

 

[Burnsy]

oooo, I just checked, the barrel moves with it, I get it now. Thanks!

Edit: a new lesson learned as a result of checking this, getting that last round in the mag to go C1 again is a PAIN IN THE ASS, with no speed loader and sweaty fingers.
