At 100 yards he's well out of effective range, and has a better chance of spitting at you than hitting you.
We're not talking 9mm RIFLES here, we're talking handguns.
Average effective range for revolvers is 30 feet, if I recall my old-west history (and these guns are normally more accurate than auto-loading pistols because the barrel does not move).
sorry krusty there was no mention of weapon type just ammo type 9mm i am assuming 9x19mm ...
Thorsim you are a luftwaffe flier mostly correct? Do you sit right behind a bomber and fire at it from 200 yards? I hope not because the luftwaffe planes were not designed for that but they were designed to drop bombers primarily or all they would have ever needed was 20mm cannons. Even if you dont accept that you should realise that in a fighting situation you are not very often going to have a con that is sitting there allowing you to shoot him from 200 yards as you please and when you do have a shot you want to knock him down quickly or his wingman is going to be shooting you.
(EDITed for obvious typo)
that is not the discussion chalenge the statement i took issue with was that a 9mm would just "bounce off" a plane skin, i think it would likely make a hole of some sort ...
as far as just sitting there, someone already pointed out that the vast majority of air to air kills were made on pilots who were unaware they were being targeted ...
BTW : some german planes were designed to "sit right behind a bomber and fire at it from 200 yards"
they are just not in the game.
nobody is saying the 9x19 MM is a good choice as an air to air weapon, but that is not the posters question.
a 9mm bullet will do harm of all sorts to an aircraft, that is all we are saying.
