I usually throw a set of VZs on my 1911s...but when I saw the title of this thread I thought for sure I'd found a replacement, however I must admit that at first glance they don't look like my cup of tea. I've found that Magpul's texturing in their rifle products to be top notch, with a number of different textures used, depending on the application. The bumps here look a little odd, and that mag release groove concerns me. I prefer a flat grip that allows me flexibility on thumb placement, and even with small hands I don't have an issue reaching the mag release. I do know, though, that Magpul put a lot of thought into their products so I'll reserve final judgment until I hear first-hand how they work.
