I just got done talking with the creators of the BlowGun and they've got some good news. They're checking out new samples from the factory right now that account for left-handed users. In addition, they tell me that a new design on the tube will get rid of the small jamming problem from using too much pressure to pull in a dart.
Maybe at some point we can add a chronometer and pressure or force measurement to the testing for a more thorough review too.
I'm looking forward to continuing to cover the AirForce BlowGuns. I think things will just keep getting better! ~Chris
