Can anyone help school me on how G-Code holsters attach with all of their brackets and hangers, etc? I want to get one of their RTI Optimal Drop Pistol Platforms. Unfortunately, they don't have a holster that goes along with my pistol setup (Springfield XD-M OSP 9mm, 4.5" threaded barrel, Trijicon RMR, and Crimson Trace CMR-208 light), but theres a couple other companies that do have offerings that come with the option of having an RTI hanger for attachment.

Do I just need to order the G-Code RTI platform along with the RTI Wheel option, and then select a holster with the RTI hanger to piece it all together?

Yup the wheel is universal to their RTI hangers. Just have to make sure that whatever holster you get has mounting holes for the RTI hanger. Use blue loctite on all the screws on the wheel and hanger. Did a 5k run and gun and lost 2 of the 5 wheel screws and the other 3 were loose half way through.

Much appreciated man!
