After handling, shooting and carrying a 30S a bit, I am inclined to agree.
My duty and personal handguns are all 45's, save one Ruger LCP and a couple of 22's. 'Serious use' falls to a grip-modded G30 or whatever 1911 I'm in love with for the moment.
If you put me on the spot, I'd keep the damned Glock.
