A blued 3" 13 has always been a "grail gun" for me. In all my years of puttering in gun shops and shows I have never even seen one for sale. I detest stainless and have never had issues with rust on my blued guns even when I lived in a very humid region. I very seldom see a 3" 64 or 65 but the blued guns seem much more scarce
That's because a 3" Model 13 in average shooter condition is worth only $500-700 or so. Most anybody with any sense would rather have a 3" 13 than $600 cash. So why sell?
