I struggled with pocket carry for several years. Kel-Tec P32, Sig 238, S$W 638, Ruger SP101, Ruger LCR, Ruger LC9. I simply couldn't find anything that was comfortable, and comforting, to carry. If it was a large enough caliber, and had decent capacity... it was too heavy. If it was a micro, like the P32, it carried well, but I felt under-gunned, and it was difficult to shoot well because of the size.
I don't like wearing a belt, so any type of waist holster was out.
I started thinking a shoulder holster might be the best for me, then I remembered I had bought a Kangaroo Carry a while back. but never wore it much because the velcro closure was scratchy. I tried it again, found I could carry a fairly heavy pistol comfortably, but the velcro needed attention. I took a black tube sock, cut out the toe, slipped it over the velcro, and now 2 years later, its still the best for me. I carry a Ruger P345 daily, and its great.
I suggest give up on pocket carry. Find a holster that you can comfortably carry a larger gun, and don't look back.
