Hello, I have a G19, generation 2. I just completely stripped the slide and lower receiver, getting it ready for some sort of finish. I was thinking of using a duracoat cammo pattern but I do not know what they look like on a glock. If you guys have any pics of cammo glocks please post them. How do you guys rate the duracoat finish? Is duracoat good for finishing the synthetic frame of the glock and does duracoat hold up on a glock? Thanks for the info fellas. JP |

I actually did the grip on my G36. Very aggressive, but it doesn't move. Makes it a lot nicer when shooting with gloves, yet doesn't tear the hands up. Check with brasspile on site here, I believe that he has experience with doing the frames in dura coat. Chris |

I had Glock redo one of my slides and barrels. To say the least I was not impressed. The quality of it was not nearly like what the guns come out of the factory. What I was told by Glock was they farm out the refinish work. There are several outfits out there now that can redo your slide for 1/3 - 1/2 less than what Glock charges and I believe they offer a better quality product IMHO. Chris |
| Duracoat works great; I did my G19 with it. Brasspile does great work with Duracoat. |
| I refinished my 9 year old Gen 2 23 two weeks ago. the parkerizing was 90% gone on the corners and 60%-70% missing on the rest. I used MolyResin, the flat-black. Preheated parts to 200, for a more flat appearance( they suggest 100 for typical up to 300 for very flat). I suspect that the more flat, may wear faster, down to a point, where the highs get wore, but the remaining finish should hold up well. It looks better that new, and seems to be wearing (or not wearing) very well. Even Blue jean rivets, scuff, but wipe out, you get the brass residue in the finish, but just like parkerized, it wipes off with an oily rag, but MUCH easier! Long term I'm not sure, but it seems great so far, and I can touch it up myself. |
glocks aren't parkerized. they have a tenifer coating that is absorbed into the metal IIRC. |

www.glockfaq.com/gunsmithing.htm#swivel The tenifer finish is an extremely hard surface preparation that is impregnated into the slide before the black parkerized coating is applied. Even if the black coating is wearing off, the slide is is still protected by the tenifer finish. Surface hardening of steel and iron (to improve wear resistance) can be done by either allowing the surface of metals to react with either Nitrogen (nitriding), Carbon (carburizing), Boron (boriding), etc. TENIFER is termed for a chemical bath nitriding process whereby nitrogen is chemically released and introduced into the surface at a suitable high temperature to allow the chemical process to take place. Using the liquid bath techniques, the temperature requires to activate the reaction is about 550 to 580 Celsius. The bath is performed in a molten, nitrogen-bearing liquid containing either cyanides or cyanates. However, cyanide-free liquid has also been used to release Nitrogen and then allow it to react chemically with steel (iron)at the surface (modern techniques). Interestingly, when using the cyanide-free liquid, Tenifer is actually the salt bath nitro-carburing technique because it starts (first reaction) with Carbon-Nitride (CN) and allows it to react with Oxygen (0)to produce Nitro-carbon-dioxide byproduct plus Nitrogen. The simultaneous second reaction takes place when nitrogen (N) is in contact with Iron (Fe) to form FeN (iron-nidride). The tenifer coating "composition" of Glock's steel slide is essentially that of FeN. It is interesting to note that FeN coating is used mainly to increase the surface wear resistance to against galling and wear. The corrosion resistance is also better for iron and conventional steel that are NOT stainless steel. Most stainless steels need not to be nitrided. The reason is stainless steel has chromium to fight against corrosion and rust (this is why we call these material stainless). However, nitriding a stainless steel will almost always lower the corrosion resistance of the stainless steel. This is because the nitrogen will also react with some of the chrominum (Cr) at the surface of stainless steel to form Chrominum-nitride (CrN). Obviously, gas-nitriding is a simpler process (but not necessary cheaper) to form a tough wear resistance coating. In this case, pure Nitrogen gas is chemically reacted with the metal such as iron (Fe) by holding the metal in the Nitrogen gas environment at high temperature allowing the chemical reaction to take place. The true FeN (tenifer) coating has a dull-gray color surface. Definitely, never black. In some applications, FeN coatings can also be polished to give a bright metal finish appearance. [SIGlock] This is not my work, simply a cut and paste from a site that has much more knowdelge than I. I have attached a link to the site as it is useful for many Glock issues. Chris |
