Since most people are shaped just about the same, I'd venture to say that gun ergonomics are the same outside of the US, too. That means you could probably find one to fit your hand just right.
But this isn't really about ergonomics. It's about being afraid of guns. You know, the gun itself isn't something to appreciate, fear, or resent. It's the driving force behind its use that you should judge.
The day I'll give up my right to defend myself with a firearm* will be the day evil disappears from the world.
(*Why a firearm vs. less-than-lethal? Well, as is typically the accusation against gun owners, I do have something to compensate for. I'm not as tall as the average guy, so I'll take any advantage I can get against someone who has no regard for my life.)
