So what you’re saying is the polymer frame is what makes it all hang together.....
I like Glocks. I have some. I don’t consider them battle weapons, however.
I have steel, poly, alum, Ti frame handguns many makes and models.
They all have been proven over time when it comes to over all usage I’ll take poly and stainless guns over the rest.
I been carrying handguns every day for over 40 some years.
The ones that get left in the safe are the blued steel ones.
