The first rule of a gun fight is have a gun. So take what you have.
That said, concealed is often better, for surprise and social reasons.
And Glocks, in general, while an absolutely fantastic handgun, are mediocre for concealed carry for a lot of people. (Some live them.)
Me, I had one slip out of my holster and drop down in the crack of doom between my front seat and the console in my car. I was scared to death the damn thing was going to fire when I fished it out.
Opted for a Ruger with an manual safety.
Options reasonably differ here.

Everyone should carry what they prefer. I prefer a DA/SA. That said, 1) Glocks have 3 safeties and I really doubt you were going to put backward pressure on a trigger, including the trigger safety, pulling it out :) and 2) WTF holster? I prefer ones with some retention like the Bianchi 126GLS one for a variety of models including Glock (not pushing Bianchi, but it’s an example; nothing’s slipping out.
Thumb breaks, grip locks like that, grippy parts that hold the trigger guard; take your pick. (Disclaimer: I hold a minute amount of RGR stock)
