I decided to drill out the hole in Part 18 where Part 33 enters, holding the leaf spring that pushes the slide lock up as well as providing detents for the safety plate. I drilled two corresponding holes in my frame (They were the thickest areas, don't worry), through which I inserted a solid pin. I slightly opened up the front post recess in Part 18 to avoid direct contact, directing the forces to our two pins, the added one and the trigger one.

The gun fires with and without the front post screw, and I think I've successfully redirected forces to the frame. I don't know if this will work for ABS frames- HK3's frames are nylon and more durable, same for Guarder. Even if the post breaks... the pins should hold the frame solidly.

... I think this is the most I've used my engineering degree for in some time.


Wow.
Wish I thought of that.
Blows my design out of the water. lol.

Have you done any testing for it, MSC?
You'll have to let us know how it handles it.

Keep in mind, most of the impact is absorbed primarily by the screw itself. If your design is able to channel the kinetic energy and successfully transfer it to the secondary post, then you my friend deserve a diet coke, a pat on the back and a patent of some sort.

The casing breaks because it's soft. Thereby, allowing some sort of give when the load comes to the screw. Thus, when the give happens, the screw casing crumbles apart. It just needs to be stronger, that's all. lol.

The basic premise of the JB WELD method is to NOT allow any movement on the inner frame. I hope your design is the same effect as that.

TO be clear as well, the gun will always run without that stupid screw installed. But sometimes, you'll get a rocky slide action.
If you want, I'll gladly donate both a tinted and a full black Marui frame for you to test it on since they are the weakest frames out of the three brands, IMO...
