I have a chance to buy a model 19 made in 1959.The gun appears to never been fired, no scratches of any kind and excellent bluing.I want this gun for a shooter and not to collect dust.My questions, will this older model hold up to today's hi power ammo? Were the guns made of that era considered to be better made by today's standards? Is $550 to high a price for this gun. Any info is greatly appreciated, ShooterJD
