Love the idea of pocket carry. I've actually been thinking about it for a while now since it's a lot easier than iwb. I've been looking at doing so with a colt .380 or sig p232. A shield might be the way to go, I've just never handled one. There used to wallet holsters for the Beretta 21a that allowed you to draw and fire the Beretta while holstered. But then the ATF declared it an NFA device or something and now they're pretty much gone. I would've loved one of those.
To summerize, yes pocket carry is great.
