As luck would have it I discovered this 3.5 mm roll pin holder works great for installing extractor springs. Just cut a small piece off of a 3.5mm o'ring, enough to fill the hole about 1/2 way on the punch.

The tool holds the extractor spring just right and prevents over compression and deformation of the spring while snapping it into the extractor.

I’ve always just used a pair of pliers and towel to make sure I don’t gouge the extractor.

That absolutely works too.

The tool is the cleanest, surest, and simplest installation method I have found and provides the best visual clarity for seeing your work.

I have not had great success with the pressing them in with pliers method and I was using the Knipex parallel jaw pliers for the task. The extractor spring needs to be securely held in the hollow end of a tool and given a twist to seat it. If you just attempt to press them straight in they will become damaged more than half the time.

Here are a couple of great videos on the best way to do this...

The Brownells punch holds the ejector spring snug enough to simultaneously twist and push the ejector spring into the ejector until you get a positive snap.

To my surprise, the Brownells 3.5MM roll pin holder punch is the one Brownells roll pin holder punch that I don't have... Just another thing to add to the cart I suppose.

You're damaging your springs!

I remember Iraqgunz talking about a tool he modified to grab onto the extractor springs so that he could give them that twist to properly seat them without damaging them... I wish I could find that thread.
