Copper to PVC for P trap

I recently bought a new vanity and sink. The old p trap is metal and leaky so I need to replace that also. I bought a PVC P-trap and also the converter to go over the metal nipple that goes into the copper fitting in the wall, however now the drain of the sink does not line up. I cut the PVC piping down as far as I can. Does the metal nipples come in shorter sizes, I think that is my problem, with the converter and old 8'' nipple it pushes the p-trap out too far. I'm so close at installing this myself!!!! Help!!!!

kcorrado, Welcome to the DIY Forums.
If I am picturing this correctly, the nipple you are talking about is just thin metal with no threads on it and is connected with slip rings that screw onto the connector at the wall. If this is correct, just cut off as much as you need to from the nipple.
If it is a solid nipple with threads, 6" is the next shortest nipple unless you have one made. Hope this helps. Good luck with your project and reply back with any other questions you may have.

It is a thick metal with threads on both ends, one goes into the wall (copper piping with a piece that is probably soddered onto the end with threads) and the other end will go into a converter 2" to 1.5" to PVC piping. Do they make smaller than 6" nipples or would those need to be custom made. I am running to Lowes after work. Also this is the right way to convert old metal p-traps to PVC p-traps? Thanks

You can get 1-1/2, 2, 2-1/2, 3, 4 and 6" nipples. Just ask for what you need. Good luck.

Ok
So it seems that because the female copper threaded adaptor that is soldered to the copper pipe in the wall is sticking out of the wall 1.24", that no matter what I use I will overshoot the drain. I tried the PVC male adaptor and even that was too long. Does the pipe in the wall need to be pushed back or shorten to make the p-trap line up?
