I had an LCP and hated it. Deeply. I carry a Walther PPK every day. It fits almost anywhere. It's accurate, dependable, rock solid, proven, and it has a decocker/safety so I can have a round chambered but have everything locked but accessible. Every person who has shot one of my PPKs (I have six) has ended up buying one.
It's a little bigger and heavier than the LCP, but not too much.
