Well, odd you should bring the topic up.
Truthfully, I haven't found a good solution yet for my Keltec P11, but the upper (watch) pocket of my jeans actually holds my pistol high, fairly secure and with just the right amount showing for a decent draw time.
Other than that, I am still looking for solutions.
I have found an interesting site that has a belly holster that looks like it might work:

Anyway, let me know if you come up with something that works.
