did you know china is copying taran and hyve mag extensions? I thought I would give a hyve copy a try. I have never handled the Hyve extension, which this is a copy of, but I cannot imagine it being any better. The extension has immaculate machining, blemish free anodizing, installed easily and has worked perfectly on my glock 43. Slide has locked back every magazine and there have been no misfeeds. I'm skeptical that this is type 3 anodizing though. It has a kind of cheaper feel to it. And it is a little slick. I am going to apply some grip tape to give me a more secure grip. Other than that, perfect. and 1/3 the price of the real thing. I am super happy. I am also happy that they aren't putting a logo on it. I don't so much mind a copy, but I'm not a fan of a straight up counterfeit.
