Magazine Modification - Legal??
I recently moved back to CA from AZ and need to buy CA-legal magazines for my handguns that came with standard magazines when I bought them in AZ. If you are alive and breathing, you know how hard it is to find 10-round magazines just about anywhere right now. So, my question is this: can I modify the factory magazines that came with my handguns to hold/accept no more than 10 rounds? I have a feeling it is legal since you can buy Magpul 10/30 magazines, but am not sure because I don't know how the conversion is made (aka permanently affixed somehow?). Any help would be greatly appreciated on this matter as I am beginning to have shooting withdrawals...
