So you used at least 4 magnets - 2 at the thigh and 2 inside (which means, the magnets do not connect directly) the gun, right? Sounds, perfect. In this case I just have to find stronger magnets than the ones I've already tested with... :thumbsup
By the way: Have to say it again and again... Stunning work on the suit...!!!
Yes! the magnets are probably separated by about half an inch in total (I drilled out some of the foam so that it was a closer fit) and the boomco obviously isn't very thick. I was pleased to find out it worked well. I was even more surprised that store bought magnets would be strong enough. But I had some laying around and they work!
Also, thanks for the kind words!
