The physics behind the Glock slide inertia trick

Yesterday I blogged about the trick of racking a Glock slide by using the slides' own inertia.

Sebastian has calculated the acceleration needed to achieve the trick.

    I attempted the trick with my sigma 9mm, it almost worked, and I’m sure it can be done, but i hurt my right arm and pectoral fairly bad. Of course it doesn’t help that I have arthritis. lol.

    I assume the Glock has a detente spring to keep the slide in battery. Perhaps this was removed.

    That was a custom rig used in the video. I’m guessing the weight of the custom slide and different recoil springs should be considered in the calculations.

    LOL … all that talking about math makes my brain hurt! I would like to hear if anyone else is able to get it done.
