Given the choice between this and a 9mm handgun with 3-4 magazines, I'd take this package in a heartbeat, especially if you could personalize it a bit...maybe a small optic. Maybe sneak an extra mag or two in the kit. A suppressor would be a good add on.
Curious, since the handgun is worn on the survival vest and this is intended to be in the seat kit, will the handgun be eliminated, or will the pilot be able to choose to have both. Given that option, I'd take both.
