I have read many times over, and not at length, that Britain banned all. 45 caliber firearms in 1909 for their Colonial areas. I have tried to "Google" information about this many times in the past and I have each time come up empty-handed.
Why did the British do this? Wouldn't those that had the desire to do the British ill have other calibers with which to do so?
Even if someone could point me in the correct direction it would be appreciated.
