William, highly likely a lemon as I have looked at the reviews at many vendor websites and on You Tube and most are excellent. Just in case, Buds offers a very low cost Lifetime Warranty for piece of mind : budsgunshop.com/catalog/warranties.php

William, It is a Sig. They have been pumping them out. If you love this gun get it. Many issues were ammunition or spring related. Easily remedied. Most issues were out of the box use without proper cleaning and lubrication. No line or model of firearm is perfect. It is only a machine. Between Sig's customer service and BUDs lifetime warranty you should be covered. BUDs has the best price around on this item.
