Here In IL we have a new law going into effect, unless a successful court challenge changes that, that will make all magazines capable of holding more than 10 rounds illegal. It will be interesting to see the rate of compliance and non-compliance. I would guess that few owners of semi autos that came standard with a magazine of more than 10 had gone out and purchased a 10 round version, just in case this NY and CA type restriction ever came here. I think the anti-gunners are delusional if they really think this will make "mass shootings" less common or less lethal.
