Sub par product, false advertising. - Elite Tactical Systems Glock 43 9mm Magazine, Translucent

The magazine can hold 7 rounds in about the same way you can fit a whole bag of chips in your mouth. You can, but you’re gonna die in the process.
Likewise this magazine will get you killed in a life or death situation. A 7 round magazine inserted into a 43 with the slide forward will result in the magazine being ejected from the gun and a full stoppage upon racking the slide. Rounds caught in the stoppage had bullets rammed inside the case me directly putting the operator at risk of a blowback or open explosion from the opened breach.

This product is dangerous at best.

Only use 6 rounds in first magazine or risk failures.

Also the 7th round really doesn’t sit well even after a breaking in period. It’s prone to popping out due to the flexible nature of this products cheaper plastic and would often dislodge when baking handled in any way.
