I have a few hundred rounds through both so I thought I'd share my opinion. P320 -Cost $500 comes with 2mags Pros: Better Trigger Better Factory Sights Better frame ergonomics Cons: Magazines are about $10 more than glock mags Original slide release is easy to hold down if you're not paying attention however there is a new one that is supposed to be MUCH better and can be changed out for under $30 Glock 19 Cost $550 comes with 3 mags Pros: Slightly better with recoil because of lower bore axis. Gun overall is a little lighter More of an aftermarket for glock. Cons: Factory sights Trigger guard should come with more of a relief for your middle finger. There are hundreds of videos on how to do this if you're comfortable taking a dremel to your gun. Final thoughts: I believe you can't go wrong with either one however I ended up picking the p320 for my new EDC. For me the ergonomics made the difference so now it's sitting with night sights and an XC1.
