adding value
 

My luger has all matching information. It has the plastic grips. Would I add value by replacing them with grips like the original ones ?

It has the most value with the grips that are original to the gun. It that happened to be the black bakelite grips, then that is where the value is. If it came with numbered wood grips, then that is what will maximize value.
But regardless, we can not help you without more information and photos too would help.
The moderators will no doubt move this thread to another column.

Everything would depend on what kind of grips you are wanting to replace.

I moved this from For Sale to New Collectors area....
