GLOCK 17的滑套和下身是什么材质的？

What is the Glock frame made of?
The Glock frame is made out of a high-tech plastic polymer called nylon 6. Exactly what that means, I don't know. But our resident engineer [MarkCO] was kind enough to provide some explanation:

Commerical price for hi-grade Nylon 6 is about $3.50/lb. Commerical price for hi-carbon steel is about $1.50/lb. Sounds to me like the Glock is actually a better buy. Anyway, I did a little research and got a smattering of information on the Glock plastic "formula". One source says "more highly guarded than the Coke formula". From 3 human and 5 technical sources, Glock uses an out-sourced proprietary hybrid polymer mix with a base of Nylon 6. The frames are cast and offer high strength, wear resistance, abrasion resistance, and good resiliency, good ductility and toughness. Fracture mechanics are excellent with defect ratios below 1. Do not compare to extruded Nylons because it is different. Casting prices range from $3-$50/pound depending on process and intricacy. The Glock is considered highly-intricate due to imbedded metallic components. Offers long term performance at elevated and depressed temperatures. Chemically stable in a majority of environments, attacked directly by strong acids and bases (better than steel actually). UV exposure results in degradation over an extended period of time. 2-3% carbon black virtually eliminates UV degradation and Carbon-Black does not become readily absorbed in Nylons offering higly increased useful life spans. Loss of mechanical properties with 2% Carbon-Black is less than 0.05% on an elevated UV exposure test equivalent to approximately 100 years. Hyrdolytically attacked by water in excess of 120 degrees. Basically, no hot-tubbing with your Glock and you will be fine. Tupperware is not made from Nylon BTW. Hope this answered some questions.
Good Shooting, MarkCO

佩服以上几位的渊博。在下是人力资源管理专业出身的，虽然当过好几年民兵，浪费过不少子弹，并且现在就职于机械厂，可是对于材料方面的知识少得可怜，最近正在学习金属材料的热处理，路漫漫其修远矣。
