More thoughts on the different things Ihave tried:
I have an Active Body holster that I have used, and it works very well. But I prefer waistband carry anyway. (I will sell the like-new Active Body holster if anyone wants to buy it).
I also tried the fanny pack carry. It works too, but the fanny pack eventually fell apart from the bouncing, and it was a little annoying, tending to rack my hoodles every once in a while.
I have thought about graduating to a Camelbak but I have not tried it yet. I am sure it would carry everything, but be slow to access.
I have also pondered about how to carry something large like a 1911. The only setup I could think of that would keep it from bouncing too much, and hold up to the abuse, is a tactical chest/shoulder harness under a bulky shirt. It doesn't seem reasonable to me though.
If I wanted more firepower, I would carry a lightweight "ready gun" in my waistband (like a KelTec) and a larger gun in my Camelbak for sustained firepower.
For now, I am real happy with my KelTec P-11 in my waistband. It has been working for me for a couple years now.
As you can see, I have put a lot of thought into this because I insist on carrying weapons and communication while I am out running. I can't believe how many runners I know that go jogging off without a single thing on them, not even a cell phone. Most runners who CCW carry at most a KelTec P-32, so I fell I am doing real well with my P11 9mm.
I had a run-in with a guy the other day, and was very glad to be armed. Out on a run, you are pretty much on your own, so it is wise to be prepared.
