I've posted about this pistol some time back, haven't made any changes yet, and haven't shot it much the last couple years.
Recently, I've been shooting it a bit more.
It's a Kimber Eclipse Target II (.45 ACP), Gov't model, steel frame. It's very accurate (for me) and I enjoy it by and large, but it has always thrown brass quite a way (10'-15') and with very little consistency as to direction, and about once every 150 rounds, one straight back in my face. Also, I've never "light loaded" it, and likely never will. I usually run H&G 68's (200 grain SWC's) at 960fps with 6.3 grans of H-Universal (love this load), I'll also probably start running some 230's (probably Lee 230 TC's) at 1,000fps with Ramshot Silhouette (this will be a hunting load, not shot frequently).
First off, I'm probably going to try to put in a new smaller radius firing pin stop from EGW. From what I've read, that'll help with the ejection issues while cutting down on wear and tear, especially with heavier loads.
I've been looking at Wolff Springs. Thinking about replacing the stock recoil spring (no one seems to brag on factory 1911 springs as it is) with either a 16, 17, or even a 18.5 lb. spring. I don't see the need to run super heavy, I'm not loading Supers or Rowlands, just looking for reliability, smoothness, and "friendlier" ejection. I'm guessing the gun has close to 2000 rounds on it, so it's probably due a swap anyhow. Any opinions or recommendations?
Is there any need to change the main/hammer spring? Mine is whatever stock Kimber is. Standard seems to be 23lb. Any need to go lighter or heavier here? Any need to replace in terms of maintenance?
Do I need to replace the firing pin spring? Ignition has seemed consistent. I run CCI 300's pretty much all the time.
Wolff also advertises an extractor spring for External Extractor Model Kimbers (mine is one of those) that is supposed to be a bit stouter. Anyone have any experience or opinions?
I've already looked around a bit on this subject, but would like to hear from the good folks on this site. Thanks in advance for any replies!!!
