I can't speak for any other manufacturer but, the only manufacturer that I am aware of the states " 500 " rounds IN the manual is KIMBER. Shoot 100/Clean repeat 4 more times... Have a problem with FTE/FTL, call Kimber and the first question asked, would be how many rounds are through the gun.
Of all the Kimbers I have owned maybe one was not right after 500 rounds, I called Kimber and they made it right.![]()
Agree on the Kimbers needing a "break in" time. I recently bought an Ulta Carry II and we are not getting along very well, FTE. But have to but more rounds thru it before I contact Kimber, if I still have the problem.
