It's great to have more 1911 part choices! Besides not having an FPS extractor slot, how are these parts different than what I can buy from EGW, Wilson, NH, etc? For example, will I still need to modify (file) and polish the extractor hook to achieve optimal placement/performance on the casing? Is the extractor properly tuned out of the box to have the correct tension? What problems are you solving?

Thanks!

The lack of the FPS, which allows you to adjust the claw-to-breech face dimension to be optimal for your particular slide is the chief difference between my extractor and any other quality brand.

A human has to shape and polish the hook at some point in the process. It's been my experience that most gunsmiths have their own idea of what they want to achieve with the shaping and polishing and would rather it be left to them.

No, the installer has to set tension. The internal extractor configuration makes it problematic to preset extractor tension due to dimensional and location differences between the multitude of different slides on the market.

I'm solving the problem of having floating dimensions between the breech face length and the extractor length, which causes the claw to breech dimension to be so large that the front of the extractor claw hits the case rebate and cams the extractor claw out away from the case rim. For years we have been solving this by either cherry picking through a selection of extractors to find one that will work with your slide, or filing off so much from in front of the claw to make it clear the case rebate and in turn weakening the claw, or having to weld up the slot of an existing extractor and relocate the slot. With an extractor having no slot and a fixture to hold the extractor in the mill, you can measure, calculate and cut and achieve optimum claw to breech spacing, which really goes a long way to making a 1911 extract and eject consistently.

Here is the problem its going to solve on my wad gun.

This is the standard extractor from a major company. My breech face to claw dimension is right at .099. The case will not even sit on the breach face without contacting the rebate.

John, what dimension do you like to shoot for breech face to claw? On your fixture does it have setscrews on the bottom to sandwich on the extractor flats or are the screws just on top. Do you have any good in process pics of use of the fixture with setup. I think I have the premise of it just would like to know it all before i mess something up. I still need to order an extractor and the fixture too!

I like to set mine for .070" for all around use, but have even tried as tight as .060"-.065". That tight doesn't accommodate scarred rims found on reloads, but on new brass it's worked fine. The fixture does have set screws opposing each other. I start with them backed all the way clear of the bore, then insert the ejector to the point that the slot behind the claw is exposed back to the fitting pad. Then finger tighten the bottom screws and snug down the top screws. I have a couple of in use pix on my web store and am working up a set of instructions with pictures that I'll post on my web site. I'll try to get it done this week. https://shop.harrisoncustom.com/hd-8...hining-fixture

Re: Extractor Tool

John,

Does your extractor tool work with 10mm extractors? Also, do you plain to make 10mm extractors?

Thanks

The HD-803 extractor machining fixture will accommodate all 1911 internal extractors, regardless of caliber. I am not sure if it will work with an EMP extractor as it is .100" shorter. I'll have to check.

As demand dictates, I will add other calibers and materials.
