Kimber is able to produce a product of such a higher quality than what was ever avalible before.
it would take many hours to get a "Pre Kimber era " Colt 1911a1 to have the fit the Kimber have.
they are 4(four) digits past the decimal point in their tollerances.
when you oil the slide rails you can feel the difference.
This is an incredible feat of enginerring.
The Fact that now with current technology Kimber is able to cinter parts, with strength and they maintain dimentional integrity under stress
who da thunk it?
Kimber changed the rules............
They are now a standard from which all 1911a1's are measured.
In my Humble opinion
