I tend to buy used guns. There are several reasons, in no particular order.
First is the economic benefit. They cost less.
Used guns have wear patterns on them that let you know how the gun is performing.
New guns tend to have locks on them, and other gee gaws that are of little use to me.
You can test fire used guns, checking them for accuracy as well as function.
There is not often stuff in the new gun counter that thrills me anymore. Owning and shooting the latest X33 mega-blaster does nothing for me.
I enjoy dropping off used pistols at Clark Custom and picking up one of a kind customs six months later.
I never have to worry about putting the first scar on the gun. I own a few pristine Smiths, but I rarely shoot them because of this. Holster and carry wear? Give me a gun that another man has eaten the depreciation on.
I still occasionally buy new guns, but not nearly as frequently as used ones. A few years ago, I wrote
an article concerning purchasing used 1911s. The advice holds true for most guns. Assuming I know about the type of gun I'm buying, I actually feel more secure purchasing used, I get a better price, and I get a gun that I'm certain I want because I have shot it.
I prefer the term "pre owned".
I call it "work hardened."
