I gaze longingly upon the polymer 80 frame kits. I’m not that mechanically minded though. But I can follow simple instructions and have a drill press.

A block of aluminum should be more durable, but perhaps harder to drill out.

No more rounds than I put through one, I'm sure the polymer would be just fine.

Aluminum is no match for tool steel.
