How?

There's some things in the realm of guns that are established fact.

Gun owners break things that are difficult to break with little to no effort.

A common complaint of the Savage Axis magazine is breaking off the plastic latch-hook.

I've often wondered exactly how they did this.  Mostly so I could avoid it.  At $45+ for a magazine, I'm careful with them.

The other end of the magazine is where I expected problems to happen.

That's the front locking "lug" for the magazine and it's common to the DBM magazine on up-market versions of the gun.  Nobody complains about bending or breaking this.

Savage improved the latch for the short actions, but doesn't seem to have done so for the long actions yet.
