It's not my preferred method, but I have carried pocket carried a Ruger LCR in a sticky holster from time to time. Works fine in the pocket, but I agree that it's not the best idea to carry in the waistband, as it's not secured.
Look at something like the Desantis Nemesis for pocket carry, might be a bit better tool for the job. It's got more support at the bottom to keep the gun oriented the right way in your pocket, plus a tab to make sure the holster comes off if you draw. The sticky holster is just a cloth pouch with a good marketing department.
If you want something in kydex, the Boraii Eagle is super minimalist, and the Alabama is aces.
