I grew up with the 1911 and shoot a CZ 75B SA in competition and love the thumb safety. I don't even have to think about it, its just a natural part of my draw. I thought when I first got the shield that the small safety would be an issue, but it turns out I can flip the safety just as well as my full size pistols. ND's are nearly impossible with a striker fired gun and thumb safety, not so without....
