WTB guns in Las Vegas, Nevada For Sale

I am buying various different handguns. I am looking for a variety of the fairly popular semi auto guns such as Glock, Springfields, Ruger, Sig etc. Please be aware that I am not going to pay retail price for a used gun. If your Glock Gen 4 sells for $539 at a discount store then I am not going to pay you $539 for your gun and I am not going to reimburse your sales tax and background check (if you needed one). I prefer unaltered guns but certain modifications are perfectly fine. Holsters add little to no value to me. Good quality top condition guns with the factory magazines and case is of most value to me.
I also buy collectible Colts and Smiths. With these also, condition is key.
I am not looking for the lower end guns such as Hi-Points, Jiminez, etc.
I have a CCW so don't worry about that.
