Evolution Gun Works HD Extractor Series 70 9mm / No Slot For Firing Pin Stop Blue. The steel available to us today is of much higher quality than what was available in 1911 when the 1911 pistol was first produced. Improvements to the entire manufacturing process include better alloys more controlled furnaces vacuum heat treat better tooling and finite element analysis-all of which EGW uses in production.EGW-specific Improvements to the original 1911 Extractor:they found that the extractor rides up the relief groove on the ammunition casing with each round fired: this dulls the hook from constantly banging the case over time tension is lost leading to a jammed case which adversely affects accuracy.they fixed all 3 of these problems by reducing the distance from the bolt face to the extractor hook.they found that most hook designs are cut straight at a right angle. they machined ours at an acute angle so that there is more surface area for the hook to bite into the case. Right angles are a they ak point on other extractors so they put radii on both sides of ours to increase strength. The hook is machined with a special cutter that leaves a nice clean radius in the inside corner where most extractors fail.they found that the back section is normally thin and they machined ours to have a fully solid back further increasing the strength. they checked slides from 5 manufactures during development and they they re all different in the back radius where the extractor is blended. In machining they left the rear face slightly longer allowing space so that a Gunsmith can custom blend the extractor to yTheir slide for a perfect fit.Lastly Their extractor is vacuum heat treated yielding great spring properties and the capability to maintain tension for 70000+ rounds. they are unable to ship this part internationally.
