Does anyone make right side promenant ambi thumnb safetys for 1911's? Ive seen safeties were both sides are equally skinny, as well as the left side being significantly larger than the right. Are their any were the left side is shorter and skinnier, and the right side is the one that is wide and long? Were ambi safeties designed to cater to left handed shooters? Yet the designs still cater for righties, when the are marketed for lefties.
