Went camping last weekend and for the first time ever, just slept with the pistol (chopped G17 with WML) AIWB. It works just fine, but I am not a tummy sleeper.
Previously I had let the gun float around the tent/hammock in the holster. That was less than ideal and I don't intend to do that any more.
Thanks to all who previously reported sleeping while carrying AIWB for the encouragement to try it. I have at least two good reasons to be prepared for any bump in the night.
