Hello all, new member here. I will start with the questions and give a little backdrop afterwards:
1. Any idea of expected extractor life?
2. When it's time to replace, what size/type and brand is recommended for the 10mm?
3. Will another brand extractor have a significantly different slot for the FPS? If so, I'm thinking I'll have to purchase another oversized FPS and fit it with the new extractor.
4. How bad is it that I fitted the FPS to the stock extractor instead of the other way around?
Back story: I purchased a Kimber Eclipse Custom Target II 10mm around 20 years ago. I purchased it because I had a really good experience with a rented Colt DE prior. After purchasing, I had some hiccups, but also didn't have the same shooting experience I had with the Colt DE, so I kept it as a range gun which I barely ever shot (at the time I was using a S&W 1006 for bedstand duty... then moved to an H&K USP45 Expert when parts dried up).
With the pandemic, I used my spare time to make some changes to a couple pistols, including revisiting my Eclipse 10mm and making some changes I wanted to do many years ago: reduced radius FPS (EGW + fitting), 25lbs mainspring, WC BP sear spring (adjusted tension for grip safety), EGW 20lbs flat wire spring with WC FLGR, solid aluminum trigger with hidden overtravel stop (fitted; medium length), steel arched MSH, and a WC 9round magazine (grip change 20 years ago).
Since the changes I've only put a box of PMC 200gr FMJ through it but had zero malfunctions (with both the stock and WC 9 round magazine). It feels like a completely different gun with the changes, although it might be because the PMC is a little lower powered (20 years ago I mostly shot 135gr and 155gr Corbon, and 175 gr Win ST). I'm pretty much smitten with the gun now, but will be doing more reliability testing/tuning in the near future.
I don't know if the image will show up but I will try submitting:
