Two. CZ Shadow for daytime use, CZ Phantom for nighttime and running use.
These two guns are of the same size, use the same holsters, mags and ammo, but vary considerably in weight of gun + trigger and sights.
Rust and bureaucrats. Freedom and vigilance. Front sight and trigger. Kindness and firepower. Situational awareness and tolerance. Safety and concealment. Taxes and allegiance. Love of man and surgical marksmanship. Once a soldier, always a soldier.
