The new Glocks have all the support they need.
The unsupported part is solid brass, not case wall. The bottom of the case is solid. Solid brass is safe until you exceed rifle pressures.
I got rid of my earlier .40s and a 10mm for their lack of support. I like my Gen 4 G22s and G27. In addition to the excellent support, the Gen4 G22 has better feeling recoil thanks to the new spring.
