Ive been very lazy.
Routinely, I carry either a glock 19 or a Walther P-99 in 9mm, usually no extra mag.
I dragged out my old Galco Miami Classic Shoulder holster for my Glock that takes two extra mags..That’s what? 52 rounds?
It doesn’t seem to be enough these days.

It's almost certainly enough for 95% of the multiple shooter events that take place. But like you, I like to hedge my bets.
You might consider the 33-round magazines for the 9mm Glock machinepistol, which if nothing else offer the opportunity to tape a pair together, giving you a convenient means of carrying 66 spare rounds that need not be loaded into seperate magazines should their use be required. And they'll work just fine in your G19.
At present the things can be had for $12.99 each *here*. And should a future high-cap magazine ban be pursued, they'll be worth at least triple that.
Horizontal carry rigs are favored by some, though the military has forbidden the use of them in Baghdad's *Green Zone.*
That does not deter some folks whio like the things, though, and find that they position the handgun underarm where it doesn't interfere with the simultaneous wear of an Interceptor vest.
