Whatever they did with the polymer engineering on this, they knocked it out of the park.

I have seen the abuse a Glock will take and keep on running. I have also seen the mangled hands of people when the Glock has a catastrophic failure. Rifles can be much worse. This still hasn't answered my question if they have tested the lower with a catastrophic failure. The aluminum lower will usually contain the blast and direct it downward in the examples I have seen. I have my doubts with a polymer lower. I disagree with the authors evaluation of the fractured lower saving the shooter from injury. I think the shooter was lucky, "compared to aluminum lowers staying together" directing the force downwards.. . https://sinistralrifleman.com/2014/12/23...r-control/ [ATTACH=CONFIG]17416[/ATTACH][ATTACH=CONFIG]17417[/ATTACH]
