Cryogenic hardened steel bullet resistant, ballistic plate

Cryogenic hardened steel bullet resistant, ballistic plate

Freeze tempering, cryogenic hardening a steel ballistic plate by bringing it to around -185 degrees celcius.
-Mainly done with liquid nitrogen.

Maybe as an extra tempering method to make it even harder.
Maybe first: Normal tempering. And baking tempering for 1-2 or more hours.

Handgun cocking with tied hands

Handgun cocking with tied hands


Important: using dry fire rounds offcourse for trying this out and for training this.
-Warning: A finger or skin maybe, might get stuck by the ejection port
And it's more only for if really needed.
It's very dangerous with a real round, because a handgun can go off because of a fall,
though most modern handguns do have a safety and it's possible to accidentually
hit and pull the trigger with a finger.


1 You don't have to tie up the hands, just holding the hands and or wrists together
  in multiple ways is possible.
2 It might be useful to warm up the wrists a bit according to my experience.


It's possible to cock a handgun with tied hands by hooking the rear sight to 90 degree angled furniture.
90 degree angled walls.
And more.

It's possible to cock a handgun by trying things out with both hands and or wrists together.






And it's possible to cock a handgun by using the teeth, but it's dangerous for the teeth and I would not advice doing it unless really needed or maybe with some padding on the biting area just to try it out.

I all thought this up myself. So it's mostly experimental.

Handgun cocking with one hand

Handgun cocking with one hand
-Only with right
-Only with left

Important: Using dry fire rounds offcourse for trying this out and for training this.
-Warning: A finger or skin maybe, might get stuck by the ejection port, but there are
                 ways to prevent this by doing it correctly.
And it's more only for if really needed. It's very dangerous with a real round, because a handgun can go off because of a fall, though most modern handguns do have a safety and it's possible to accidentually hit and pull the trigger with a finger.

You can single handedly cock a handgun by rotating the gun 90 degrees downward and then
pulling the slide with 4 fingers while the thumb  holds the handgun in place and also pushes down.
