As to seeing the sights and your tartget, at night, at any distance over 6 feet or so, tritium sights or a laser are about the only way you're going to be able to get hits, short of a shotgun. Try it sometime...with or without flashlight in the crossed wrist mode...you'll be a believer. I'd opine that most defensive shooting is done in low light situations...you be the judge. Rod
I can manage about 10-15 feet accurately after that the light difference between the sights and the target make it difficult to get the pistol pointed in exactly the right direction. After you get muzzle flash from the first shot than everything goes to pot.
