For anybody interested I sent my newly acquired Glock 21 off to have the retro slide cut and the new extractor that is a factory Glock enhancement modification on the second gen .45 models and it came back shipped to me in less than 3 weeks all done.
Beautiful job on the re-application of tennifer on the slide and when it was delivered to my door it was put in a brand new Glock box (I shipped it to Georgia in a cardboard box packed with newspapers) complete with new manual,cleaning stuff and mag loader. Just thought I'd pass this information along for what it's worth. |

Quoted: For anybody interested I sent my newly acquired Glock 21 off to have the retro slide cut and the new extractor that is a factory Glock enhancement modification on the second gen .45 models and it came back shipped to me in less than 3 weeks all done. Beautiful job on the re-application of tennifer on the slide and when it was delivered to my door it was put in a brand new Glock box (I shipped it to Georgia in a cardboard box packed with newspapers) complete with new manual,cleaning stuff and mag loader. Just thought I'd pass this information along for what it's worth. Good news: Your rebuilt G21 will be as good as new for years to come. Corrected news: 1st - Glock does a good job picking the subcontractors to farm out the recoloring of the slide. They don't do that part in house. I'm not sure if they do the actual machining in house either. 2nd - The tenifer Glock uses is a surface hardening chemical treatment of the slide material, not the black coloring. Per Wikipedia: Glock, an Austrian firearms manufacturer, utilizes this process to protect the slides of the pistols they manufacture. The Tenifer finish on a Glock is the third and final hardening process. It is 0.05 millimeters thick and produces a 64 Rockwell C (diamond cone) hardness rating via a 500 °C nitride bath. The final matte, non-glare finish meets or exceeds stainless steel specifications, is 85% more corrosion resistant than a hard chrome finish, and is 99.9% salt-water corrosion resistant. After the Tenifer process, a black Parkerized finish is applied and the slide is protected even if the finish were to wear off. Several other pistols also use this process including the Walther P99 and Steyr M/S series. What's the issue here? Glock can't re-tenifer the slide in this country because of OSHA regs and I'm concerned that the area that was machined is now devoid of the tenifer treatment. What, if any, long term strength, wear, fatigue, cracking, or rusting issues in the areas not currently tenifered and therefore 'softer' is not my area of expertise. |
