Blued steel looks best with that pistol. If I wanted it fancied up, I'd get that super high polished 'royal blued' you see on the fancy gold cup 1911s.
This, but on a HiPower... I think what makes a 1911 look good often compliments a HiPower (obvious reasons)
Interesting but I prefer "old school" (probably cuz I'm old).
If you are a HP collector and have examples in different finishes, I'd say "why not?". They are great guns regardless of finish.
I have a Sig with that finish. It is a pain in the A$$. You cannot get any kind of solvent on it or it will peel not to mention it just ain't right to have that kind of finish on a BHP. I have the epoxy blue/black finish on my HP and it looks good. I like the finish on the HP that JNieman posted above.
the pic I posted is a 1911, just for the record- but if I wanted a fancied up HP, I think that's the route I'd go. Traditional colors/finishes, but done on a higher level of pretty.
