Now why am I thinking about the never ending story of the Regulations rewrite?
Taily's bush lawyer look at the draft reg quite correctly points out a loophole which any competent Barrister could drive a Road train through!
So, can a Pilot, flying his own aircraft from point A to point B carry his own Firearm in his personal baggage?
Any responsible firearms owner would ensure that the firearm itself is rendered temporarily unusable. In the case of a semi auto pistol such as a Beretta 92 he would remove the magazine, store that separately and fit a triggerlock.
The ammunition is also stored separately in a locked container, away from both gun and magazine.
So what's the answer?
