LOL - I thought about having that finish done while my "SP-01 Compact" was there, but I guess I was too anxious to get it back ASAP after the "long" wait and didn't want to add more time on top of it. Guess I should have done then. The SP-01 could be another candidate though...and it is still there. Hmmmm
Don't call and ask David about his experiences with Hard Chrome and why he thinks having the electroles Nickel under the Hard Chrome is even better. If you do you'll want it for every gun you own! Trust me, I am struggling with this problem now. I just need a lot more $$$$ then I'll be happy! 
I was looking for a black finish, and I had narrowed it down to either a black nitride finish, or black hard chrome..I e mailed David, who explained to me that the black hard chorme wasn't very durable, so I went with black nitride. I have a g19 I carried for about 3yrs , many times in the summer I've sweat all over it. To this day, there's no rust on it except for the aftermarket rear sight which does rust up, if I don't keep a eye on it. One nice thing about nitride, is you can do the barrel inside and out. Honestly, I wish CZ would offer some options for finishes besides polycoat, which at this point in time, I'm not real impressed with...
