You can have any gun you want, as long as it's not too big, too small, too inexpesive, too accurate, too inaccurate, holds too many rounds, holds the wrong type of rounds, can be modified to hold too many rounds or fire the wrong type of rounds, looks scary, "might be dangerous", or that could be misused by a criminal, an idiot, or a mental patient.
What are you people complaining about?
