When it comes to small parts assemblying them can be confusing at times. For the extractor assmebly, the Striker Safety Spring connects to the Extractor Dperessor Plunger (does not matter which end of the spring attached to the plunger) as long as you hear a tactile click. Lastly, attach the Spring Load Bearing which will click into the opposite end of the Depressor Plunger Spring. Once this assembly is complete the Depressor Plunger will go in the back of the slide first and push against the extractor (the spring load bearing should press against the striker plate). The extractor is an OEM part stamped with "1895".
