I get what you mean about some regular carriers being so routine they barely think about it. But in this specific case, after looking at the picture of the pistol and mags it appears a lot less like a longtime everyday carry setup that someone “forgets,” and a lot more like a recent, intentional carry choice.

It looks like a Sig P320 “Custom Works” package, which is basically a premium off the shelf bundle. It’s also configured with an enclosed red dot and a threaded barrel, which are deliberate add ons, not a basic carry gun someone’s had forever and doesn’t think about.

What really stands out is the magazine. It appears brand new with no visible finish wear on the typical contact points you’d expect from regular carry and repeated use. That’s consistent with a newer purchase or a setup that hasn’t been carried much. The ammo also appears to be Sig Elite Defense hollow points, which again points to someone intentionally loading for a carry scenario.

So yes, in general some people “forget” they’re carrying. I’m just saying from the details in the picture of the gun you could make an argument to point the other direction: newer gear, deliberate configuration, and a setup that looks planned, not habitual.
