New S&W 1911 - Need help finding grips

I just bought a sweet new 5" blue carbon steel 1911 with fixed sights. It shoots great, but the grips are a bit thick for me. I was thinking of combining slim alumagrips with the finger groove panels that can go under existing grips and wrap around the front. The problem is that I can't figure out who sells them. I thought it was pachmayr, but they don't list them on their website anymore. Does anyone know where I can get them?

kel - this is better I think in autoloaders - or even accessories - but let's try autoloaders for now and see if you get some useful input.

That it is pierce that makes the finger grooves I want. Hope this helps someone else.
