Not every body need to train to that level to defend themselves from criminal. Lots of criminal's are taken care of my people who load their guns and only pick it up to use it when needed.
Is that a tenth of a second from a holster highly unlikely.
Or is that a tenth of a second when sights are already on target. Or how many tenths of seconds are you talking about.
Training and practice is a good thing the more the better but to say one needs to be the world best isn't real. Most people do not have ready access to a range nor the time to do it.
Should they do more yes will they most likely not. It is real easy for gun people to get down on non gun people for not shooting enough. Would I like most every body who carries to train more yes I believe it is a good idea.
Am I going to stop people who only shoot once a year or less from being able to defend themselves no.
So whats the answer Train help others train take classes past the info on ect. Become an instructor helps others learn and take them out shooting.
The average criminal is probably only a Level 1 himself. Remember that it is illegal for a felon to touch a gun, so you won't see many of them putting range memberships on their credit cards, making visits to Thunder Ranch or doing IDPA competitions
