I was told, on good authority, that the real reason RAF aircrew got the PP was because the number needed roughly matched the number given up by the Protection crowd after the Princess Anne failure. The other reasons were made up after to justify it.
Loved the Browning. Couldn't hit a damn thing with the PP. In fact the PP is the only weapon, ground or air, that I haven't got top rating on.
Will be buying a Browning or a Sig P226 with my own money.
