As I understand it, Victor is the elected colony representative so he should be able to authorize John to print a weapon - handgun and/or rifle - as they begin to encounter more threats. Or heck, get the Robot to print one - he had no issues getting around security protocols when he printed the handgun for Will.
The fact that the robot is learning human values from Will and should know nothing about the human race except by his interaction with Will, I have to wonder how the robot knew it could print a weapon in the first place. And it seems to know that it's kind (robots) are dangerous to humans so why not build a weapon that blasts hot plasma shots like the robots use when attacking?
And, no, Maureen has no input into this discussion. She has made it clear that she is smarter than most others by her input into building the Resolute but she has no concept of defensive tactics - her SEAL husband does. Let him contribute to their survival by using his skill set developed while in the armed forces.
