I know this isn't the subject of the post, and I can't really add to the suggestions you've already gotten, so I want to ask for curiosity's sake: why do you carry your gun when you are mowing the lawn? (Not a slam, I'm really wondering why.)
When I come in from mowing the lawn, I am drenched in sweat, and I have dirt and grass clippings even in my underwear (I usually wear shorts and a T-shirt when I mow, and the dirt and grass seems to get inside everything.) It's so bad that most of the time, I stand at the back door (we have a privacy fence, and we live out in the country) and strip down and hose myself off before I come in the house. It's hard to imagine putting a gun through that! (Again, not slamming you, I'm really wondering why.)
