I had a G19-3 a few years ago where the slide finish was slick and had that orange peel look to it. Very nice and even had a slightly slippery feel.
Now my 4-15-13 G19-3 is the more typical boring phosphate look and feel. What was the difference? |

The old process versus the new process, the process was changed due to EPA concerns with the chemicals. Actually, the finish has nothing to do with the tennifer treatment. You could polish off all the black (shiny or matte) and the metal should still be as corrosion resistance. Glock has gone back and forth with finishes over the years; Gen 1 & 2 guns are flat, Gen 3 are shiny, and now it looks like Gen 4 is back to flat. Different models and runs within each Gen can also have different finishes. |

It has nothing to do with generations, I have a gen 3 19 with the slick grayish orange peel finish, and two gen 3 26's, one has the same finish as my 19, the other has the Matt gray finish that is very fine with no texture in the finish.
I have seen gen 4 19's with both finishes as well. I think 2013 was the start of the new finish, 2012 was the end of the slick grayish orange peel finish. I prefer the orange peel finish, it's like the inside of a non stick skillet. |

The finish it self changes from time to time. I have several from earlier this year with a more shiny finish, but a new 27 with a dull almost parkerized look to it. A month or two from now they could go back to being shiny again, but why Glock does this I don't know. I like the shinier look myself. Glock did stop using the Tenifer process several years back, but as most should know, that's just a metal treatment not the black that's on the slide. What they use now is something akin to what M&P's use, which is melonite I believe. |

Why do people keep referring to the orange peel finish, I haven't seen any that remind me of an orange peel......
I've seen what I think are 3 finishes and maybe I'm combining them incorrectly. I've seen the "old" shiney black finish that was common on gen 3s but I don't see it anymore on new gen 3s. I see more of almost a flat black or dark gray on current gen 3s like my g27, and then I see the shiney gray for lack of a better description on gen 4s like boy my 4s. Maybe they have nothing to do with generations but that's what I see in gun stores now. |

The phosphate finish is different than that process. It seems both we're changed around the same time though. |

Is the corrosion resistance still the same with the new process? Yes, same if not better according to the armorer instructors. I've not seen any more reports of rust than I did with the old ones. (It happens but it's rare). Same. No difference other than some milky blue color on some barrels, something about the finish bonding. My 19 has it but its no big deal. |

The old process versus the new process, the process was changed due to EPA concerns with the chemicals. The Tennifer vs the nitriding has nothing to do with the exterior finish. They used Tennifer for 25 years and there are a handful of different exterior finishes with that. |

The last finish change seemed to happen around the same time. The only difference is the bluing on the barrel IS from the process change. The armoer trainer said there was something about it that didn't allow the finish to stick to the barrel as well, hence the blue color you see sometimes rather than the dark black barrel. And I'm not talking about the slide finish, just the barrel. |
