Personally, I think the least amount of manipulation to the firearm (even holstered), the better. I think taking the firearm off of your body and setting it anywhere is a bad idea. For IWB carry, I do the following and it works great (assuming you wear underwear)
1. Unfasten belt, unbutton and unzip pants
2. Lower pants to mid-thigh and refasten belt (looser than when around waist)
3. Lower underwear and wrap underwear over grip of handgun (as well as mag pouches, if applicable)
4. Lower entire assembly of pants/underwear/carry rig to ankles
Gentle outward pressure with each leg (tension against fastened belt) will keep your weapon vertical and within easy reach. The underwear completely covers all exposed areas of the firearm and mag pouches. It's safe, fast, easy and completely elliminates manipulating or removing the firearm in any way.
