Smurf,
This is a great subject. I hope all here will take time to post their concerns and remedies.
Naturally, where/how you carry, the type weapon, hoslter, and clothing you wear will present different challenges.
Two very common things I see are: "Strap Traps" where a holster fitted with a retention strap is utilized, and "Garment Stalls/Traps".
Strap:
When trying to draw quickly or simply under pressure, it is easy to "pop" the snap, grab the pistol...BUT leave your thumb on the strap during the initial draw. This usually results in only a "stalled" draw, but someone in a full blown panic might not figure out what they are doing in time.
Garment:
Another common problem occurs when any article of clothing (shirt, blouse, vest, jacket, etc..) is allowed to hang loose near the grips, or is not properly "cleared" prior your draw. What happens most often is: You end up with a handful of garment and grip!

The outcome of course, is a slower draw (at best). In fact this happened to an old knife instructor of mine recently when when we got together to shoot with Longtooth.
He (instructor) had allowed his shirt (tucked in) to become blousy on his strong side, when he reached down to draw...he pushed part of his shirt down on top of the grips. It wasn't too pretty.
Anyway, I'll shut up now and see what others have to contribute. It is well to consider what works best for you, and you have shown yourself astute by recognizing the need.
Good question!
