Carry methods are not only dependent on the situation, but also the user. User preference can vary.
I have half a dozen or more cargo shorts. I got them for summer wear.
I also own several pairs of different styles of cargo pants (not a 5.11 in the bunch, either), which I originally used for work (range instructor), but now wear for retired/casual roles (fits right in with where I live).
My preference in cargo shorts is for styles which have deep front pockets. That allows me to conceal pocket-holstered guns of many makes/models. The front pocket drops and centers the weapons, without allowing them to "tip".
The side cargo "bellows" pockets don't "center" the weapons, but allows them to shift anywhere front-to-back of the pockets, and worse, to even "tip" over. The weapon goes from muzzle down to muzzle forward or backward.
Yes, my variety of snubs and plastic or metal-framed pistols become easily shifting lumps that swing and bump into the outside of my leg (not enjoyed by the iliotibial band, or the side of my knee). That's just standing and walking. Running is a lot worse.
Sitting? The weapon in the front pocket can be gently shifted to slide over against the outside of the leg, resting on the seat next to the leg, but still mostly held against the leg. The cargo pocket holstered weapon can flop out away from the leg, and then there's the issue of having to make sure it remains muzzle down, instead of shifting/tipping in the generous cargo pocket.
Yep, not all pocket holsters are the same. That's a subject worth a thread of its own.
Now different folks are built differently, and different cargo pants are built differently, and there's a pretty wide potential variety of possible "fits" of folks and shorts (with different pocket styles and locations).
I like to have some control over the way a weapon (holstered) fits in my pockets, and I prefer to really limit the potential for looseness and uncontrolled shifting of a weapon. I especially don't appreciate having a pistol or snub revolver flopping in & out, banging against my IT band or the side of my knee.
When driving around "town", I realize I'll have to stop and unbelt in order to gain access to my front pocket holstered weapon. When on long road trips, if I have a front pocket holstered weapon, I'll either have another weapon securely close at hand (carefully positioned case, for example), or I'll shift the pocket holstered gun to a different pocket, like the inside breast pocket of a jacket (light or heavy, depending on the weather).
FWIW, I've invested many years carrying and using my pocketable guns from the various pockets, in both cargo pants, jeans and in jacket pockets, so I've ingrained some habits in realizing where they're located and accessing them for live-fire practice and training. (That's one of the admitted advantages of working a LE-only range.)
Now, I neithe shill styles/brands of holsters, nor do I pretend to have the ability to pick and choose carry methods for others. I can discuss and demonstrate in the classroom, when NO ammo is present, as well as out on the range, and let others decide for themselves.
Regardless of what someone else thinks they like, or wants to work for them, once the whistle or buzzer sounds, it's safe & smooth drawing, presentation and accurate rounds-on-target that matter.
The threat won't care about how cool or tactical your carry method is to you, or looks to others. It's a means to an end, which is keeping your weapon safe, secure and accessible. You get to pick, and be prepared to live (or not) with the consequences of your choice ... as do we all.
Best of luck. Choose wisely.
It got recycled into vise soft jaws (leather) and a splash guard for a horn relay on my Nova (the Kydex was almost the perfect shape), with the Chicago screws salvaged for later use.
