I was planning on putting one sliding trigger clip on the back of bag and a U-bolt on my belt. Just enough to stop it from sliding. I have a few things on both sides of my belt so I was afraid that I wouldn't be able to slide it around as far as I needed if I had it through I belt loop.
Nobody calls me Lebowski. You got the wrong guy. I'm the Dude, man.
Have really liked the ease of a sling bag.
Stays put and easily pulls to the front when needed.
Tennis ball tubes are nice for plugs.
Current slings don't last long though.
Pliers ,knife and such stay on the web waist belt.
Just my 2 pennies.
