I'd highly advise finding a shop that rents and try them out for yourself. I just went through a similar purchase picking up a LCP, and then a Glock 26.
While you can't beat a mouse .380 for concealment, as many have said above, it's not very accurate, or fun to shoot, and ammo is very expensive if you want to shoot it lot.
The LCP is OK in a you-get-what-you-pay-for kinda way, but I don't find it very accurate, it's slide is not so smooth, and fit and finish are about what you'd expect from a $260 gun. I guess I'll keep it as an option for minimalist wear, but I don't feel well protected by it, and I don't mean due to the caliber.
Just bought a G26 Gen 4, twice the price, weight and size, but OMG... I love this gun. My groups are way better at 25 yards, vs the LCP at 25 ft, it's fun and cheap to shoot, fit/finish and smooth reliable running can't be beat.... Now this gun makes me feel safe.
While still not pocket carry for me, I found a truly minimalist holster that I like very much and wear at 3:30... the
MIC holster, which I also like for my G19.
