Now just so some of you folks know and realize, the 1911 model 45acp was NOT designed to be shot with a chopped off short barrel or modified feed ramp! Some of these minor problems happened to Kimber and other manufacturers as well. Now perhaps it was parts coming from out of the country I don't really know for a FACT!!!
However, when you start speaking of a 1911 model in a .40cal Smith & Wesson, that is a whole different ball of wax gentlemen. The only time my Kimber "carry gun" ever JAMMED was when my daughter wanted to shoot the pistol. She limp wrists pistols and didn't know how to shoot the gun that day. It has never JAMMED on me or the wife ever.
I have read a lot of BS about KIMBER'S so called problems with those who own Kimbers, usually someone's buddy (no name or account of facts) that has had major problems with his KIMBER model 1911 45acp!!! Then when I aske for a phone number, so I can varifiy the "true facts" that person justs fades away......never a come back.
Now any factory rifle or pistol coming to you, can have a minor problem or two. I have gone through this with Winchester, Colt, Remington, Marlin and Browning in the last 45 years. Only once was I ever left hung out to dry. Thank you Remington!!!, New JUNK model 742 in a 30-06. I solved the problem, traded the rifle in on the best hunting rifle I ever owned, a new Belgium Browning FN in the .300 win mag.
