Evolution Gun Works Practical Extractor Series 80 9mm/38/40 Blue. However the 1911 extractor that comes with the pistol as well as most aftermarket steel and aluminum replacements is very heavy and if fitted improperly can cause the 1911 to fail to fully eject. Due to this and several other factors the extractor wears down and requires replacement after a short time. The EGW Practical Extractor solves this problem as well as many others by offering a practical design that doesn't necessarily need to be overly expensive. The hook is one of the weakest points on a stock extractor as it is cut at a right angle and right size. Other companies will machine the extractor at a right angle and have it sit proudly at an acute angle. This allows the hook to better bite into the case reduce wear and produce more force. The hook is machined with a special cutter that leaves a nice clean radius in the inner corner of the extractor. Vacuum heat treated yields great spring properties and the capability to maintain tension for 70000+ rounds.
