Comes with T-Rex Arms IWB holster and the two Wilson Combat grip modules. The plan was to take full advantage of the modularity of this platform. The X-macro module was so that I could buy a threaded barrel and a compensator. This will allow the comp to sit inside the dustcover of the macro grip and create a sleek looking macro comp build with a real compensator. All you need is the barrel, the comp, and a x-macro mag; making this the ultimate EDC gun setup.
