I just picked up a Michaels of Oregon bandoleer holster. I agree that when I got it, I was thinking it would not work very well. Then I made a couple of changes and now I am pleased. What I did was lengthen the shoulder strap until the bottom of the holster reached about to my belt. Then I purchased a second strap from Bass Pro and ran it through the loop at the bottom of the holster around my waist. Now it is like a cross draw holster but the shoulder strap holds the weight of the scoped Dan Wesson 44 mag. You might try that.
