Glock in Slow Motion

I'm not sure what this is trying to prove, but I have heard that the flex in the frame helps reduce felt recoil. I'm sure the lower weight compared to steel frame guns make this a bit of a wash.

I do have to wonder if that amount of flex would be seen when being held by a human hand.
 
oh noooo! it FLEXES! all firearms must be 1000% rigid or they will break and shatter into a million pieces killing you and everyone you have ever known and loved! trololol </sarcasm>

all firearms flex when fired, all of them. it's just a question of how the shock of firing is absorbed and transferred, if the material has sufficient flexibility and strength there's no problem.

as for the people who will pop up claiming this will lead to horrible accuracy, the projectile leaves the barrel before the flex really sets in, furthermore, the slide and barrel are both steel and interface directly. So long as the barrel and the sights are joined in such a way as to consistently return to the same relative positions accuracy is not affected.

The only real inherent mechanical problem with polymer frames is short stroking due to limp wristing. A polymer frame has less mass, so it has less inertia making it more likely to be pulled along with the slide's recoil, this problem is solved by not being a girly-man and learning how to shoot properly.
 
Are you guys ones who love the AK family????

Here's an all steel AK firing:


WHO KNEW, there's internal vibrations that cause things to whip about.....

Now, if you're an AK hater, and love AR's, here's one for you:

Flexibility vs stiffness. Stiffness isn't always a good thing. A deformable body acts differently during transfer of energy...minimizes internal stresses. Stiffness = force / displacement in simplest form, one degree of freedom example. Holding displacement constant, force is proportional to stiffness so if the frame didn't flex as it did, expect a greater force acting on it.
