I keep posting this every few months but here goes again!
When a gun seems like a bargain because it has a defect, some people only look at the "great price" factor. They aren't realistic with themselves! They sometimes talk themselves into believing that they can "buff it out, tweak it in their basement, or it is just an issue that won't bother them. Most of the time they are wrong and usually spend more in the long run than to purchase a gun without the defects in the first place. They now will have a gun that has been "played with" at a no bargain price.
It is my life's experience and honest opinion that most times it's just better to walk away if one has to make excuses, ask about repair work before they even buy it, etc. I am not talking about someone purchasing a gun as part of a project or similar, but just as a regular gun to be used and carried.
There are many many good guns out there that when looking for a used gun, when I see more than just a minor scratch, or a part I can easily replace myself, etc. I walk away and continue the hunt. I've yet to not find what I am looking for. After all,,,,,,, "the hunt" is fun! LOL!
