Lets see. It don't hurt nothing. And it might help... Hmmm...
Damn obsolete gun!
I guess it would be a better design if it had a safety on the trigger face that could be activated by putting the gun into a holster that has a bit of untucked shirt in it. Or maybe it would be a better design if it had an external extractor that flys out the side of the gun in the case of a catastrophic failure, forming a great secondary missle. Or maybe it would be a better design if it had a high tech 12 pound creepy trigger? Or maybe it would be more advanced if it locked up on the barrel hood, instead of top lugs, that way it could be much fatter and harder to conceal.
There is nothing wrong with the grip safety. If you can't activate the safety with your grip, get a beavertail with a speed bump. If you don't like grip safeties, there are 200 other types of pistol that don't have them.
