concerning holsters; there is a vast gulf between the average holster and a good quality one. thumbsnaps are no slower than without, *if* the holster is well-designed. during the draw cycle, your thumb should cut thru the strap automatically. if not, you will have a hard time drawing under pressure.
one of the *big* yet unsung advantages of certain autopistols like Glocks is that their slide geometry is perfectly configured to allow a thumbsnap strap to retain the gun yet line up with the thumb during a draw. I haven't messed around with wheelguns much, but I am sure the custom holstermakers know how to do a thumbsnap model that draws quick.
