Thanks for the info Ratbag- I thought any hole at cruising altitude would cause a violent decompression. I take it you mean .380 if you are talking issue Walther?, a less powerful round than .38 special, but still capable of penetrating plywood! As someone who obviously has some familiarity with firearms how many civilian aircrew would you trust with a pistol? Although it's four years since I last ran a pistol course, the gun handling of experienced military, police and civilian shooters filled me with horror and I can't believe it's improved much since! However, I'm sure that if I was in your position, I'd want my Glock back!!!
