Doesn't bother me, hardly know it's there...but I realize it seems to aggrivate a number of shooters; there is a wide varitety of after market ones of various shapes to proove that not all are content with the standard one.
Do remember one conversion (from quite a few yeara back) that replaced the whole back strap assembly into one big grip-safety device...didn't work as a grip safety, but whn you squeezed it, it cocked the hammer (Caravel?). Some of the really stubby cut-downs (Dectonics) did away with a functioning grip safety completely.
Doubt many gunsmiths would recommend removing an existing safety system or pinning it out of play but such things have been done in the past. Given the modern version with the trigger activated firing pin block safety, the grip safey really isn't all that useful.
