My Garand was a CMP with a new trigger group, a 4-67 Winchester barrel and a Springfeild Armory receiver #3,448,XXX.

With a clean rifle, firing match grade ammo, the firing pin doesn't indent the primer very deeply and fails to fire about one in eight. Do I need a new firing pin and is there a good sight for take down and repair?

Call CMP and talk to them about it.

I would check the mainspring (hammer spring) first.

Here's some online M1 manuals:

This site has basic disassembly and even includes a video.

This site has a lot of good M1 info.

Once you have the rifle field stripped, inspect the firing pin to insure the tip is present, in good condition, and protrudes enough.
Inspect the REAR of the firing pin to insure it's not broken or deformed.

Inspect the hammer spring to insure it's not weak or broken.

Contact the CMP for help, and replacement parts. If you bought the rifle from them, they will almost certainly GIVE you replacement parts.

Thank you for the information. The sites are very helpful. It looks as though the firing pin may be deformed, slightly bent, and won't be difficult to replace.
