My A-80 broke. Repeatedly. The promise of an all-steel "poor man's SIG" was unfulfilled.
It was a bad surface hardening treatment. First the slide stop lever, where your thumb goes. Functioned but you couldn't manually engage or disengage any more. Replaced it with a spare from a .45 ACP parts kit I had. That one lasted. Then the dismount lever broke, and all I was doing was firing it!!!
Not that much recoil stress on a part not moved during the firing cycle!
It was the pressed-on lever part that you manipulate, not the important cylindrical part that holds things together. Also replaced with the spare, that lasted maybe another 800 rounds. See end of story.
Then the part of the slide that covers the recoil spring cracked. It's silver-soldered in, like Llama's are, but the STEEL is what failed.
I succumbed and bought a new slide assembly.
Thought life was good, then the ejector BENT!!!
Bent it back but never trusted it again.
I sold it and never looked back.
