Try loading 7 rounds into a Garand.

Yes I know. They sell two and five round clips, but the gun still has an 8 round mag (depending on how you define mag).

But the original Colt .45 ACP was 7-round magazine.

The Garand device is called an “en bloc clip”.

Different from a magazine, and different from a stripper clip.
