A couple of years ago I decided I needed a true pocket pistol. The improved LC9 wasn't out at that time. The Taurus TCP reviewed pretty well. I wish I had never bought the TCP, and I never shoot or carry it anymore. The sights are like warts. The slide has to be pushed home even when I slingshot it hard. My hand frequently engaged the mag release when I shot it. I was frequently having to slap the mag back home. I polished it and put in an aftermarket trigger but the TCP is still a pain in the behind.
If you get a heavier pistol (TCP is about 10 oz empty) for better slide action and a gun with better sights you've creeped up in weight to where you no longer have a true comfortable pocket pistol. You might as well buy a 15 oz P938 or an 18 oz Shield. Neither of those are pocket pistols. Even at 15 oz the P938 has annoying felt recoil and is not a lot of fun to shoot. It's not as accurate for anybody in my family as a Shield. The Shield is more comfortable to shoot but it isn't anywhere near as accurate as any other gun I own.
I learned from my small pistol experiment, but I'm through with lightweight guns. After we ditched the P938 my next purchases were a PPQ M1 and a VP9. I'm keeping the Shield and the VP9 but giving my PPQ to my son. Since then I've bought a 75B SA, a 97B, and a P-01 compact with steel frame. I've learned I want a bigger heavier gun for accuracy and comfort. YMMV.
