You can download source archives for any package using build --sources, like
this:

    $ guix build --sources emacs
    substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0%
    43.3 MB will be downloaded:
      /gnu/store/c4xfnis0g5g2v1ssl3wqgk8h6s3xjfk6-emacs-29.1.tar.xz
    substituting 
/gnu/store/c4xfnis0g5g2v1ssl3wqgk8h6s3xjfk6-emacs-29.1.tar.xz...
    downloading from 
https://bordeaux.guix.gnu.org/nar/lzip/c4xfnis0g5g2v1ssl3wqgk8h6s3xjfk6-emacs-29.1.tar.xz
 ...

    /gnu/store/c4xfnis0g5g2v1ssl3wqgk8h6s3xjfk6-emacs-29.1.tar.xz

You can then extract the archive somewhere.

Hope this helps,
Tomas
