Are there any restrictions on magazine capacity for firearms in New Hampshire?

New Hampshire does not have any restrictions on magazine capacity for firearms. This means that there are no limits on the number of rounds a firearm magazine can hold, regardless of the type of firearm (handgun or rifle). Options B, C, and D are incorrect because they imply that there are restrictions in place, limiting magazine capacity to either 10 or 15 rounds. While these restrictions may exist in other states, they do not apply in New Hampshire. Therefore, the correct answer is A.
