I like pocket carry. Many guns that are called pocket guns are a little big for me. It all depends on what pants you wear and how deep the pockets are.
I have a first gen LCP. The trigger pull is crazy long and even with my average large hands it is hard to shoot. I put a laser grip on it because the sights are non existent. It is hard to shoot, snappy on the recoil and shoots a weak round. That said, I carry it more than anything else. It is probably the easiest to carry of all the pocket pistols. It is tiny and weighs almost nothing, something like 13oz loaded. After all, having it with you is rule #1.
I have an early Kel-Tec PF9, the gun ruger copied to produce the LC9. They have a terrible reputation and mine was very unreliable with many types of ammo. Thankfully it shoots a mild reload of mine with 100% reliability. I have put well over 500 of my handloads through it without a single jam. I can pocket carry it but it is as big as I can comfortably pocket. If you have big pockets and don’t mind just over a pound in your pocket the LC9 would be a viable option.
Lastly, get an airweight J-frame. I love mine and I carry it whenever I can. I switch to the lcp when I need the ultimate in ease of carry but in my opinion an airweight j-frame is the best pocket gun available. Mine has a steel cylinder and weighs about 14-15 oz empty. You can get one with a titanium cylinder that is closer to 12 oz empty but it costs way more. I went steel because I shoot mostly .357 in mine.
