Everyone has their own comfort zone. Mine extends to only having standard-capacity magazines which were available pre-2000. I don't judge anyone for interpreting the law in a more permissive fashion.
I will say that I don't believe rivets and/or epoxy are required to legally limit a standard-cap mag to 10 rounds, as long as the capacity limiter will not fall out unless manually removed.
On an entirely unrelated note, I'm a huge fan of Vibra-Tite for ensuring that friction-fit parts don't separate unless you want them to.
