I bought a new Mossberg 930 SPX today. My 13 year old grandson and I put it through its paces with about 50 round of everything from slugs and buckshot to birdshot. It ran flawlessly throughout. I love this weapon. My head told me to get another pump, but lust drove me to the purchase. I have absolutely no regret. It has none of the problems about which I've read, and I'm quite pleased.
