Glock 48 vs Glock 19 if OEM 15-round mags become available?

With the news that OEM 15-round mags may be coming for the Glock 48 / Glock 43X, let’s assume they end up being reliable.

If the capacity gap basically disappears, which would you choose: G48 or G19?

I live in a place where I’m allowed to own only one pistol, so I’m trying to pick something that balances shootability, comfort for carry, and concealment.

Some context:

• Mostly office work
• 5’7” / 170 cm, 30” waist

The main purpose would be rare emergency self-defense. In my area, licensed civilians may need to respond to shooting and stabbing attacks in public places (bus stops, streets, malls) until police or soldiers arrive.

Curious what people here would pick and why.
