I currently own a Kimber and a Smith & Wesson .45.
They are both very good guns.
The Smith is 20 years old (I bought it new) and carried it as my duty gun.
The Kimber is brand new and a dream to shoot - it comes with a lot of "gunsmith" custom work already done to it.
Everyone knows how good the Springfield is -
So I guess I'm saying "get the one you want" - the one that really turns you on, because all three models and brands are outstanding.
