So @Duke's love affair with his S&W Performance Center M&P has gotten me thinking - is there something different about S&W's barrel porting compared to Glock's much disliked 'C' series pistols? What is working better about S&W's execution? I noticed in Aaron Cowan's latest video he is sporting a GEN5 G34 with a ported barrel by Agency Arms which looks a lot like the old C series treatment. Typically we've seen the "Roland Special" Glock builds use compensators vice ports...why aren't we seeing a GEN5 MOS 'C' model, or what does Glock need to do to make that model desirable?
