Peters Stahl 1911 Pistol Bench Evaluation

AGI’s Gene Shuey looks at a very unique pistol–the Peters Stahl 1911. With several design departures from a more traditional 1911 as well as the capability to easily change caliber, this is one different 1911 from what we are used to. These are not easy to find guns, and probably priced accordingly, but one of these is certainly on my wish list!

Next week we will show the field evaluation of this pistol with AGI’s jack Landis, so watch for that.

  1. Wow, neat gun. I instantly noticed the secondary extractor on the left side of the slide. When Shuey shows snapping a cartridge under the extractors you can see the usual negative hook characteristics of the secondary extractor (the left extractor that is) for the usual good reasons (for ejection purposes).

    It must be made in Germany or Austria.

    Thanks for the video.

    • Hi Swhiffin.

      Good question and I understand where you’re at with it. If both extractors have positive hooks then there would be a problem with ejection because the ejector will not be able to force the case off the extractor hooks. IF the ejector was able to force the case off the two positive extractor hooks then the empty has the tendency not to be ejected out of the gun (the empty would tend to drop and remain in the gun and a jam would occur as the bolt cycles forward). I will explain more …

      The left extractor (also called secondary extractor) hook has a negative angle because it’s purpose is to aid in “holding” a cartridge (via its spring tension inwards towards the breach face, same tension the primary extractor has also). It doesn’t perform as an extractor, that is it’s hook does not purchase the cartridge rim and extract it from the chamber – the primary extractor does that.

      The primary/right extractor should have a slightly positive hook angle. The purpose of this is to hold a cartridge. When there’s two extractors they cannot both be negative and they cannot both be positive. One must be positive (the right extractor) and one must be negative (the left extractor). If the left extractor was positive and the right one was negative then the cartridge case would want to eject to the left, which is why we need the right extractor hook to be positive and the left extractor hook negative so that the angle of ejection is correct (ejects to the right).

      Since the left/secondary extractor has a negative hook angle (as secondary extractors should have) it’s hook will lose it’s grip on the cartridge rim as the case bumps into the ejector. There are many kinds of guns that have a secondary extractor and they serve the same purpose/function as I described here.

      If you have a gun with a primary and secondary extractor (such as a Mossberg 500 shotgun, etc) take a look at how the left extractor does not perform extraction but rather only holds a cartridge during extraction until the ejector contacts the fired cartridge case. You will see when the ejector contacts the empty cartridge case how the negative angle on the secondary extractor hook loses its hold of the empty case. You will also see how the negative angle of the secondary extractor aids in the angle of ejection towards the right side, which is why the cartridge case will/should eject out and to the right.

      Hope this helps. Cheers.

      • The Stevens/Savage Model 87 semi auto .22 rifle is the same way. Two different extractors, and two different extractor springs. Very minor differences, but don’t switch them.
