Carry weapon choice is highly subjective. You've chosen - so far - a semiautomatic pistol. But there are lots of sub-categories within that group that will suit different shooters.

Do you want a sub-compact pocket pistol in 380auto, or a more powerful, larger cartridge in a larger pistol?

Do you want a single action trigger with a manual safety, or a DAO trigger?

To help answer some of those questions, do you want to pocket carry, IWB, or OWB? What's your body type compared to your wardrobe? How often are you ok with leaving your piece behind?

For my purposes, I carry a Ruger LCP daily. The Gen 2 is fantastic, and very affordable, so if you happen to get it taken by an over-zealous LEO and it disappears in an evidence locker, you're not out much cost. I have a Gen 1, a Gen 1 with a Galloway conversion, a couple Gen 2's, and a Pro. Hate the sights on the pro, but I get what they were trying to do, and it's really nothing more than a Galloway trigger. The Gen 2 standard trigger is 90% as good as the galloway trigger, I wouldn't buy another galloway for that reason.

I carry the LCP because I can carry it every day, no matter what I'm wearing. Even if I'm carrying another larger, more powerful pistol, I often still carry my LCP. It's cheap, reliable, and plenty accurate. I won't enter a debate about the killing power of the 380auto - I'm very confident in its ability to do the job at self defense ranges, should I need it. I carry over a dozen different weapons over the course of a year, but my common carry piece is the LCP.

Other CC pieces that I would recommend:

Pocket 380's:

Ruger LCP - DAO, cheap, tiny, light
Sig Sauer P238 - SA w/ Manual safety, great trigger, heavier, night sights, tiny
S&W Bodyguard - DAO, tiny, light enough, safety, prefer the LCP though
Glock 42 - Love this pistol, but very expensive for what it is. Glock trigger (heavy SA).
Kel-Tec P3AT - Cheaper, less refined LCP

"Little too big for pocket" larger pistols:

Sig Sauer P938 9mm - SA w/ Manual Safety, great trigger, heavy, night sights
Ruger LC9 & LC9s - DAO, light, small, FLAT, the LC9s has a better trigger than the LC9, I have both, I still carry my LC9 a lot.

Compact pistols:

Springfield EMP 9mm & 40S&W: SA w/Manual safety, heavy, 1911 style, great triggers, naturally
Ruger SR40c: budget friendly, 'glock-style' trigger, nice that there's no bluing to wear
Glock 19 9mm & 36 45acp: heavy SA triggers, bluing wear is a consideration
Springfield Micro Compact 45acp (or any Officer model 1911): single action w/manual safety, heavier, less capacity, flat profile
Bersa Thunder/Walther PPK: 380auto, larger, more capacity, heavier, very mild recoil, can be had DA/SA or DAO, decocker safety

Don't overlook revolvers though. Ruger SP101 and S&W 60's, Ruger LCR's and S&W 640, S&W Bodyguard 38, all of these make great concealable wheel guns, with plenty of punch on the business end. The all steel models are better behaved than the alloy and poly models.
