So I've been running under a misunderstanding, I believe.

FSP is Front Sight Post. - So it entails anything that uses sights?

Threat Focused is everything that doesn't use sights?

Front Sight PRESS. (If I'm not mistaken)

It's also referred to as Front Sight Focus. The meaning of which is self-evident.

Using iron sights on a pistol, usually means focusing on the front sight when composing the sight picture (and sight alignment).
