What is the "non-sporting" & "points" tests?
When I was looking in to getting a Glock that struck me as odd that the .38 wasn't able to be imported into the US.
(BTW I settled on a G30)
It's all one thing. The law talks about sporting purposes, but with respect to handguns the BATE (I think) came up with a points system to determine which handguns were "sporting" and which were not. I'm not sure of the details, but things like safeties get you points, but being big does as well. The Glocks in the less powerful chamberings were likely too small to be importable.
