Actually, the bill is so poorly written with phrases like "designed to be readily converted" that it may, in effect, ban ALL magazines with detachable floorplates, regardless of capacity, and things like colt lightnings if you can fit more than 15 .45 cowboy specials or .38 shorts in the mag tube.
Regardless of anyone's position on how bad the policy side of the bill is, the legal, regulatory, and Constitutional problems are just rampant in this thing.
Looks like it may make the ballot in Nov, though, so hopefully it will be short-lived, if Hick signs it.
