In another forum someone told me there is supposed to be a washer between the top of spring and that black top. Can anyone confirm?
Does this spring look faulty? GEN 4 19
I recently purchased a glock 19 gen 4 and it is jamming almost every shot. A guy at the NRA range looked at the spring and said it looks defective. I have one on its way in the mail it got shipped out today. Notice how the top left part of the spring is coming up over the plastic piece. He said it should not be doing this. What do you guys think?

It doesn't look like a current part to me (more below).
When you say "jamming", do you mean that it's not ejecting empties, or is there some other symptom?
If it's not ejecting empties, it could be that you are "weak wristing" the pistol and not holding it firmly enough to make the recoil system work. This is pretty common.
Otherwise, it could be ammunition with a low power factor that's not producing enough recoil to make the system work.
The former problem can only be fixed by you. I'm not saying you're doing that, but it's possible (I've done it myself).
The latter problem can be fixed by calling Glock and telling them the story, and asking them to send you a new RSA. They might tell you to use "124 grain ammunition", but that's not the right answer.
The photo below shows three RSAs for a Gen4 G17 with no bevel in the front of the slide (THIS MAY NOT BE APPLICABLE TO YOUR GUN):
Left: the one that came with the gun, looks like the one in your photo. It is not marked on the back.
Middle: an aftermarket assembly.
Right: the new RSA, marked "0 2 1" on the back (for the Gen4 G17). Notice the cup that sits on top of the spring, under the polymer piece that sticks into the slide. This cup made the whole RSA fit much better, and along with spring rate changes (I think) it solved the feeding problem and the occasional problem I encountered when the spring hung up on the slide when I was field stripping the gun.

Check the metal end of your G19/4 recoil spring assembly. If it does not have "0 4" stamped on it call Glock and have them send you one.I recently purchased a glock 19 gen 4 and it is jamming almost every shot.

If it is stamped "0 4", do some serious cleaning on it! With an "0 3" spring it should be working great with 124 grain ammo. Good luck.
The photo looks normal. The guide rod (black rod with button on top) needs to go through the round "thingy" on the bottom front of the slide.
The spring must not go through the round thingy on the bottom front of the slide. That would be bad! Hence, the spring is slightly larger than the
guide rod. Don't mean to over-simplify, just explaining it like I would to my wife! LOL
