Been shooting and carrying a Kimber for more than 7 years.
The only problem I ever had with them is when I take my reloads that don't pass muster and use them for practice. But I am prepared for that and expect it to malfunction.
I do this to actually practice clearing malfunctions . . . . .
When I use reloads that pass muster I never, NEVER have had any problems.
As far as factory ammo goes . . . . No Problemo . . . . .
Both of my Kimbers are full size and I switch off half way through the year.
I shoot two to three matches a month between March and October.
I practice in between matches . . .
Now you have the other side of the picture.
Good Luck
