I've just about decided it's too big for a pocket, but I've been experimenting with different ways to carry a SIG P938.
I have conventional belt holster, appendix IWB, compression shirt with built-in shoulder holster, and pocket holster.
The "sticky" pocket holster is a bit too bulky for the front pocket, and it doesn't keep the gun oriented butt-up in a cargo pocket.
I've also discovered that the weight difference between empty and fully loaded makes quite a difference in comfort; loaded, it seems like I have a large pendulum in my pocket.
