Around here, worn, "shooter" Model 19's start around $500.00. Add in better than average to NIB condition, then add box and papers, and you're pushing on up toward $600.00-650.00. High? I don't know. They get sold.
I don't worry about what something sells for somewhere else. All that matters is what's right here, right now. I won't lose a gun I want, that they don't make anymore, over $50.00 or even $100.00. Sure, I might find another one for less. On the other hand, the next one I see might be another $100.00 more.
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have everlasting life.
John 3:16 (NKJV)
