I have two kimbers, one pro (4” bull) and one government (5”). The pro is much older. Its a I versus the newer 5 inch is a stainless II. Both in 45.
the extractor in the pro finally gave out so I replaced it. I purchased a wilson series 70, installed, went to the range for a tune. Before the old extractor tip broke off in the pro, it had been 100% reliable with all kinds of 230 and 185. After a couple of range and tune sessions, I am having failure to feeds. So, I started some comparisons between the two guns and the two extractors. Short end of a long story, I have purchased a kimber extractor (finally back in stock). I’ll try to remember to check back in after the kimber extractor.
Here are some side by sides. In the guns you can see the newer full size has some extra machining. In the close up of the extractors you can see the kimber machining has a thinner claw, and more machining. I’ve found that the wilson does not like certain cases like PMC. The kimbers claw fits much better on brass.
