I use it mainly as a cleaner for the barrel and slide. I also use it to lube the barrel and locking lug/slide. I still prefer a grease for slide rails on a metal framed weapon. And on really gunked up weapons I like to douse them with gunsrubber first then coat them with CLP.
I've never had any issues. I prefer the liquid as it lasts longer and smells infinitely better. What's your definition of "sufficient"?
Know the status of your weapon
Keep your muzzle oriented so that no one will be hurt if the firearm discharges
Keep your finger off the trigger until you have an adequate sight picture
Maintain situational awareness
