All metal treatments, even high-tech ones, have “side-effects.” Nothing is perfect!
For external guns surfaces, polymer is a good choice. Robar’s version is Roguard or Poly-T-Two. Both are very acceptable, and can be an any color.
Also suitable for external surfaces is QPQ, otherwise known as Tennifer or Melonite. Very hard. Also very suitable for rifle bores. However, it is so hard that subsequent machining is nearly impossible!
For internal parts, NP3 is the way to go. NP3 has integral teflon, which gives it natural lubricity. However, it is slick and thus not the best choice for slides. And, it has a silver/grey color. Other colors are not possible.
“Hard chrome” plating is obsolete. There are superior choices for surface treatment today. Hard-chrome barrels are notoriously inaccurate, because of inherent unevenness of the plating.
Nickel plating is also mostly …Read the Rest
