I needed an adapter to hold magnetospeed v3 on a python. Without adapter, I couldn't get the distance right between sensor and bore, and because of the shape of the python, it would just slip off anyways.

I made this adapter by downloading this stuff off grabcad: https://grabcad.com/library/magnetospeed-rail-adapter-for-glock-1

I then modified the glock adapter part, to hold a python. Since the top of my 2020 python is angled, the strap doesn't sinch down quite nicely, but it still works. perhaps i'll make a top part too if it becomes a problem, but really I just keep an eye on it

Thank you to the community, having these files made the process go much faster, and FWIW, 22gr H110 and 110gr XTP out of 357 mag, makes for one spicy meatball
