Thanks everyone for your "likes" and your comments. I probably should add this comment. When I bought the gun it looked basically brand new, externally. However, the internals were by far the filthiest of any used gun I ever bought. The barrel had been swabbed but that's about it. I think I know why this gun was so dirty, the owner couldn't get the slide off the frame! The slide would stick at one certain point and would go no further. I had to wrap both of my thumbs around the rear sight and very carefully exert a bunch of pressure, but it finally came off. After a very thorough cleaning and lube the slide is starting to come off much better, not perfect, but I'm sure that soon it will behave like my 3rd Gens and 1st Gens.
