That didn't really seem like the point you were making, but yes, clearly. The best example would be the Kel-Tec PMR-30, which has an explicit note right next to it.The point I was making is that there were AR based handguns on the Maryland Handgun Roster before FSA'13 that had >20 round capacity, but because of the Maryland magazine law we were limited to only 20 rounds.
Not quite as open and shut as that, but it'll be a point in our favor. Just getting back to 20rds would be tremendously useful, as I'm sure we all are discovering.If the 10 round limit fails, 20 rounds should be out the window too.
