hard chrome is about the most durable finish there is. Unless you scratch it with another piece of metal, or drage it across the cement, it will not mark.
Hard chrome is a great finish, and I prefer it to stainless, but hard chrome will wear from holster use.
This is about 10 years of daily use, some of it in a leather holster, but mostly in a kydex holster.
The black streaks are actually polished bright and not black. The finish did its job very well, and rust was kept to a minimum. The pistol was originally Colt blue, which held up remarkably well considering the conditions it was placed in. It lasted about six months without any rust, but the SE PA summers, me sweating like a pig, and riding in a constantly wet leather holster did it in. The best thing I ever did was get it chromed, and switch to kydex.
I paid about $200 for the chrome job about 12 years or so ago. If your planning on using it for a carry gun, its worth it. If you just dont like Springfields finish, a good park job will probably cost you about $100. My buddy and I used to do quite a bit of parkerizing in his garage. While you can do it yourself, you do need a bunch of stuff, and unless you intend on doing a lot of it, just pay to have it done. A good park job does make for a nice finish, especially on military guns.
