I wish they would stop calling standard capacity rifle magazines "high capacity" to try to play them up as being in some way unusual
10 rounds isn't even really standard for pistols, basically every full size pistol comes with a magazine larger than that (for reference, the most common US police duty pistols, the Glock 19 and 22, come from the factory with 15 round magazines), smaller than that and you're getting into compacts that are meant to be more easily concealable (which itself has its own risk)
I'm fine with restrictions that make sense, but trying to say that full size pistols (with magazines >10 rounds) are "high capacity" and "not commonly used for self defense" is just patently false
