| So my favorite plinker, an early Springfield 1911A1, has developed an extractor clocking problem. I'm gonna get a new oversized firing pin stop and likely a Wilsons Bulletproof extractor. Which is better the EGW stops or Wilson's? |

Quoted:
I went with the Wilson BP extractor and FPS on my DW Valor. I've used the BP extractors and like em. The BP FPS I would imagine to be square bottomed too? I want to try a smaller radius on the bottom to see how it effects recoil and reliability, if the Wilson's is squared I'll probably try it. |

I used an EGW oversized stop, a fine file, a diamond bench stone, and a Sharpie. I filed for width first, until the stop would just enter the slot. I then worked on the upper radius, applying Sharpie and filing gently where I found the ink had been rubbed off. Then the firing pin finally seated into the stop under pressure from the firing pin spring, I very carefully put the slightest radius on the bottom of the stop by dragging it across the bench stone, then stropped it on a business card treated with jeweler's rouge. Taking my time, I spent maybe 45 minutes on this project.
Since doing this, I've found that I can run a 23 lb. mainspring and a 14 lb. recoil spring with perfect reliability. Muzzle rise was noticeably reduced, even with the stock 16 lb. recoil spring. I think the longer dwell time has made helped improve feeding, as well. |
