On a wish list thread here I posted that Glock should,
Build a G19 sized gun with a slimmer, dedicated 9mm, slide.
Ditch the stupid thick plastic wrapped mag in favor of a steel one,
then make the gun grip slimmer to fit the mag.
Glock built the gun. (As a single stack with the plastic mag)
Shield arms saw the obvious, and built the mag.
I didn't start that, obviously.
It was simply obvious.
