Gray deagle with suppressor, tactical belt with holster. I attach the deagle to the holster in inventory. I put the the deagle on the quick slot circle ( RB). While the deagle is in hand, if I select it on the quick slot it goes back in the holster. While the deagle is in hand, if I select another item in the quick slot, the deagle goes back into inventory in clothes or backpack instead of back into the holster. I believe this is true with other pistols. If you are close to capacity in inventory this can cause a problem. If I switch from pistol to axe, I may not be able to put the axe back into inventory and select a bandage, for example, because the pistol is taking up inventory that was used by the axe.
