From the HRA website;
Hawaii state law prohibits greater than 10 round detachable pistol magazines (including rifle magazines capable of use in any pistol, such as the AR-15/M16, AK, M1 carbine, H&K carbine, Thompson, and aftermarket Ruger .22 magazines) unless blocked to hold 10 rounds or less and “not readily restorable”. Possession of illegal magazines is a misdemeanor, and possession of a handgun with one inserted is a class C felony. There is much debate among gun owners, law enforcement, and dealers over the interpretation of this portion of the statutes when rifle magazines which fit handguns are considered, and the prohibition is not generally enforced.
If we start building legal AR pistols with detachable magazines would that give a reason to start enforcing this law?
