Extractor Replacement Help for USP 9mm

Can anyone tell me step-by-step how to remove and replace the extractor of a USP full-size 9mm?

Or where I can find a video or booklet with pictures FREE?

Cheese, It's super easy to do in about one minute or less. You'll notice that on the slide above the extractor is a little hole. Inside that hole is a roll pin. You take a punch that is a little smaller than the hole and place it on the roll pin, and then tap out the roll pin using a small hammer on the punch. If you don't have a punch, or you don't have a small hammer, it is absolutely no problemo. You can use a finish nail of the right size (head first, tap on the pointed end), and you can use anything ya got handy as a small hammer. The roll pin comes out pretty easy. Try to catch the extractor and it's spring as you remove the roll pin so you don't have to go looking on the floor. The extractor is under moderate spring pressure.
^^^ What orfeo said above. Here's a pic for reference (courtesy of Big Bore). I'd try to tap out the roll pin from inside of the slide, to prevent possible marring of the slide.

Thanks a bunch. I'm going to home depot to buy a set of brass punches for this.

I would get this set. They are roll-pin punches, not regular punches. They won't damage the roll pin's head. I got one set and am extremely happy with it.

Check eBay, I picked up a nice Lyman set there.
Thx for the heads up. I think home depot actually sells roll pin punches.
Brass punch is too soft.

You need a steel ROLL PIN PUNCH. 3/32" as noted above. Even Sears hardware should have it. You can get it in a week from Brownells too.

Should I put some oil on the pin before tapping it back into place?

Yes, on the pin, but not extractor.
Not to go against TooSixy, but I would not oil the roll pin, nor clean it. Once you tap it back in, you want it to stay put. It is not a moving part. The less you mess with it, the better. I have removed and installed my share of 'em. The extractor and it's groove are best oiled and then wiped dry. The reason not to really oil them is because it doesn't usually need it, and because it will only attract more crud if it is wet.
