I suggest the first thing you do is close the toilet seat. Way to many people dropped their CCW into the toilet.
That being said since I use a QuikClip

Holster I can easily unclip holster with gun in it and there is almost always somewhere in the john I can place it while I take care of business.
Keeps handgun accessible so I'm not caught with my pants down (figuratively)
No worry of it being seed or falling out of holster while I have my pants down (literally)
Just make sure you don't forget it in the John.
