I've decided that my next build is going to be a pistol, mainly for home defense but also a range toy. Just wondering what the choice of sights was for those of you that have them. Probably going to mount a small light on it since it will be for "things that go bump in the night". Would Magpul MBUS be as good as anything? Small red dot? Other options? I'm going with a 7.5" barrel/upper if that makes a difference.
