Welcome aboard.
It may be a bit finicky with low brass at first, but they usually become more forgiving with a little break-in. Although like KW said, his has been flawless since day one. We've got a great group of folks here on Mossberg Owners and the atmosphere is very laid back. The only thing we like better than discussing each other's guns is lookin at 'em, so we're lookin forward to pics of your new SPX and other Mossbergs. Take a look around and feel free to post up pics of any other firearms you own in the various sub-forums. You'll find that we're into a lot more than just Mossberg around here. Jump in on the conversation anywhere and let us know if you have any other questions.
Enjoy the site!
