Hello, all. First post, but long time S&W lover. I just purchased a "new" M&P 22 Compact from a reputable vendor on GunBrokers and noticed a few issues with this gun.

1. There is noticeable wear on the slide where metal meets metal. There is also a good amount of gunpowder build-up. The vendor said that they don't have the means to shoot the gun and sold it as they received it.

2. The slide bounces up and down the frame and has noticeable clicking. See video here (with sound):

3. The ejector moves around a lot. It moves up and down as well as left and right. See video here:

How much of this is normal?
