Now go run 50m a few times and do a back-flip onto your couch wearing it.
I'd really look into a positive retention holster, especially with a cockd and locked single action. Doesn't have to have a shroud, but I would never trust a simple tension grip holster on a gun that wasn't just for something like sitting around doing security. The leg strap definitely helps deter muzzle flip when drawing. I'd cut down to 1 pistol reload and either save the weight or add a rifle mag if you think you don't have enough rounds; always keep the rifle fed over the pistol. If you haven't already, check to make sure that when getting down prone, the rifle/pistol mags can be accessed and aern't literally up against your hip bone.
You'll also notice that the more stuff(and larger) you have on the mid back area will cause the belt to not want to curve; additionally, crouching or trying to sit/lean on terrain while shooting will be interesting.
