In addition to the adapter you need x2 M3 short brass inserts to be installed underneath so that you can use the original screws of the TM Micro Red Pro Sight to secure the red dot to the adapter (needless to say you need to remove the picatinny rail mount that comes with the TM sight). You also need 1 longer screw than the ones that come with the AW adapter (bundled with the HX1102 for e.g.), to secure this adapter to the slide. I am not 100% sure of the thread of these screws, I just found one screw that fits the threads on the slide (they are not M3, M3.5? if you know post the info). Be careful attaching the adapter to the slide so that you don't damage the threads!
