I agree. I had a CZ compact(99021) done in black nitride (melenoite, tennifer, same thing) anyway, it turned out great, however as someone pointed out, doing small parts may /may not be a good idea, a few weeks ago I dug the little CZ out and took it to the range, it's stupid accurate to say the least. When I got home and I went to field strip it I found the slide stop had broke, odd, as the gun has a low round count, maybe 1000-1200rds on it. To their credit, CZ promptly replaced the slide stop free of charge, and had a new one to me within a week. The more I think about it, I think that when the slide stop was nitrided, the shaft of the stop became brittle, and since it bears alot of stress when the gun is fired, it snapped.. I also had the saftey levers black itrided as well, but I don't expect any problems there, as these see little use, and aren't under any kind of stress when they are..
I've also had a little experience with Robar as well. I had bought 3 of the PX4 mags that they sell that are already coated in NP3+ . I carry the PX4cc daily, and carry a spare mag as a reload. After about 4-5 months I noticed that the NP3+ was peeling, and rusting..I called Robar, and they asked if I would send them pics, which I did. I called a few minutes after sending the pics, just to make sure they got them, and they were shocked, they told me that it looked like the metal prep wasn't done correctly and the finish peeled and rusted. They then told me to box them up and they'd redo them, and ship back to me, as well as expedite the process. They e- mailed me a recipt when they got my mags, with a completion date of 6/20/18.. On 6/20 they were delivered to my doorstep. The mag that was rusted, pitted, was recoated with NP3+ I assuming that the metal prep was done correctly this time. It has pits from the rust, but it appears that they've been throughly cleaned out, they're smooth to the touch and I'm wearing it right now. I don't expect any more problems.
