I discovered the perfect way to carry my NAA Pug .22mag nasal spray dispenser in the right front pocket of my Duluth firehose pants.
If you feel around in the right front pocket there's a little inner pocket down at the bottom.
It's the perfect size for one of the little NAA revolvers.
In order to keep my Pug from chewing a hole in the pocket lining I cut the finger out of a pair of leather work gloves and use that as a little holster (I cut the tip out of the middle finger and then turned it inside out so the stitching is away from the gun).
When I'm carrying a real pistol AIWB I often carry the Pug in my pocket either loaded with rat shot as a snake charmer or loaded with .22mag solids as badguy nasal spray.
