Am I not tactical enough if I have never "press checked" a gun?
I have a simple rule...if a magazine is in the gun there is a round in the chamber.
You're letting your inexperience show. It has nothing to do with being tactical.
Anyone who has shot any courses of fire with different round counts and mag reloads might do one on the line. It checks readiness of the pistol before the next round of fire.
It's part of many shooter's rituals.
Some courses of fire may or may not use all rounds in the mag. And if you're someone who rides the slide lock and you shoot a mag to empty, well you might have a empty mag loaded with an in battery slide and no round in the chamber. (Well, except for you)
We do a press check before holstering to see what's going on. Now you know if you need to reload before you start the next round of fire.
You've obviously never had to store a loaded pistol somewhere out of your possession. That's fine too. Many have to under certain situations. Hours or days later when you're strapping your shit on, you do a press check for piece of mind and operational readiness.
It's 3:30 a.m. And I'm posting from my phone, I'm sure I could throw a couple more scenarios out there, but I'm not.
Press checking is more of an "admin" pistol ritual.
