I am getting close to ordering my first suppressor. The gun will be a 9MM Sig 226 with a factory threaded barrel and I am leaning toward a Gemtech suppressor. Now here is my question - what about the sights? Most of the guns I have seen with suppressors mounted appear to have sights too short to be functional. Should I order tall sights for the gun? Pardon my ignorance on the subject. Thanks.
