I don't know if I spelled it right but what is it? I didn't know much about Glocks, my only experience being with a monster bby Glock in .45. Perhaps a G-36? years ago. Worse little gun I ever owned. Kicked like a mule and the ergonomics and me didn't mix at all. I kept hitting the mag release under recoil among other issues so I got rid of it. Now I love them and own 3. Being a newbie Glockster I came by one in a trade. I had a Styre M40, lousy, lousy, gun retails for $410 or so. I wanted rid of it but everyone I delt with knew what they were like and I couldn't dumpt it wihout taking a money beating. Along comes a guy with this funny looking Glock I .40 with all the goodies, box, etc., but the slide was nickle platedd. ( I thought) Anyway the guy never heard of Styre and I convinced him he could not livve without it. An even trade but I believe I made out as his Glock was a g-22 with extra including a .357 Sig bareel. Didn't even know what a .357 Sig was or that they were so easy to install in the G-22. The G-22 is now a .357 Sig, I like te round that much. So what about this Tennifer coating deal. I've since learned the guy I traded with POLISHED the G-22 slide bright metal, like stainless and it looks nice. Did he take the coating off?
