Do you like black or silver?
I like black, and just had a HiPower refinished in Melonite QPQ by Drakes Gun Works.

It runs around $200 for most guns.
Melonite is about as close as we can get to Glock's Tenifer finish (best part of a Glock, IMO) in the USA due to the nasty chemicals used to do Tenifer. Melonite is basically a heat treatment that colors the metal. It actually surface hardens it to a few ten thousandths. Here is some info on the process:

Here are some pics of my gun after the treatment:
I think it looks "blacker" than in the pictures.
It's odd in a way, since it's a nearly smooth texture, but still non-reflective.
Drake did a good job prepping it, as he noticed such things as the thumb safety's extension was silver soldered (I had not even realized that). The Melonite process gets to some pretty high temps, although not quite to silver solder temps. But to be safe, he chose not to treat that part. He black oxided then Telflon coated it instead, which matched perfectly.
One nice thing about Melonite is that, supposedly, even if the black coloring wears off, the metal is protected against rust since the treatment goes INTO the steel a few ten thousandths. Again, think about Glocks- you see the black worn, but no rust.
I only have 500 rounds on mine since getting it back, but there is zero finish wear on anything like the slide rails or even the lug in the frame which the barrel cams on- things that wear first. There is a little shine here and there on those places, but no wear.
