I carried one in my pocket as a BUG for nearly 15 years. It was always reliable and surprisingly accurate for such a small pistol. Only thing I didn't like about it was the small sights.
I finally traded mine for a Glock 42 last year. But I wouldn't hesitate to carry the LCP if that was the only pocket gun I had. There is a new version of the LCP 380 out now with bigger sights, and a front night sight. I'll probably buy one of those when I find one for a good price.
Here's the one with better trigger and front night sight. It's called the Custom Model
