Also consider the condition of your hand at the time you reach for the gun.
As stated above, smooth may make for a quicker consistent hold for some, but hands can be dry, wet, slimy(fishing), oily etc etc.
Kayak fishing requires a different gun/grips than standup in a boat or shoreline/bridge fishing situation.
Hands are always, anything but dry in the kayaks, and I carry a 380 or 45 with checkered grips.

As I said to Pachmayr long ago, why would anyone not carry your rubber 1911s when fishing or in the Swamp.
I might add that the first time I met a really big snake, why was I not carrying a shotgun.
