I have found that I can carry my GLOCK 27 in my front pants pocket (khakis, not thin suit) just about as easy as I can my Kel-Tec PF9. There is a trick to it. I didn't used to think this would work. But I have discovered that if I use a partially zippered P3AT gun rug as a holster, it works. I don't know why, but it works. The draw is speedy enough, too. The outline of the rug masks the pistol outline. It works. So, my G27 will be my pocket carry from now on on week days, when I'm wearing khakis. P3AT in my suit pants on Sunday. Note: I'm carrying with an empty chamber. I know some will think that heresy, but it's not a real holster, and I'd rather be safe from any possibility of a negligent discharge. Here's a photo:
