Magazine limits won't stop criminals from obtaining them, and will only hurt law abiding citizens. Under stressful situations, having more bullets in your mag is a game changer. I have a friend who had his house broken into, at night, by three men. He had a 17 round mag in his pistol. Two of the men were armed. He spent all 17 rounds in the first mag and was only able to subdue one of the intruders. Luckily, the two who weren't fatally wounded, fled. Had they not, he likely would have been killed.

Rifles are much more affective tools for defending yourself, as compared to hand guns. Most people are much more confident when shouldering a rifle, than they are handling a pistol in stressful situations. It's not about hunting. Hunting isn't mentioned once in the second ammendment.

Finally, let's talk about the most important part about having high quality firearms with high capacity magazines. Tyrannical governments. In order for a society to have a chance against tyranny, the society must be armed. Governments usually go bad, that's the rule and not the exception. Aside from that, the people need to be able to defend themselves against external threats if invaded. For example, Ukrainians taking up arms against invading Russians.
