How to lower line count in 3ds max without losing shape detail?

rememba_da_name

I want to reduce the poly and line count inbetween the edges that actually make the shape without losing the shape itself. No matter which optimizer i use it ruins one or more of the lines or curves that make up the gun. I am willing to pay money to get a plugin that will save me time so i dont have 10k lines to optimize but maybe less than a 1000

Post pictures - there's a bunch of different ways to approach this but without pictures it's hard to tell what will work well.
