I did look for problems with the gas system but that appears fine. Thanks in advance for tips.

I purchased a new Sport in early October. I was just able to put the first rounds through it over Thanksgiving. Using American Eagle 223 and a Thermold 20 round mag my Sport functioned perfectly regardless of loading technique. No jams. Very accurate-3 of 5 touching at 25 yards with open sights. Empties land at 4:00 about 6 feet back. Very happy with my Sport.
From the problem you describe I suggest sending your Sport and the mag it came with back to S&W for warranty. Your Sport is basically new. At least give them the chance to evaluate it and repair or replace the upper.
My Sport had a cosmetic defect when i received it--the barrel was scratched, maybe when the FSB was installed. I bought the Sport through the Internet and the seller would not exchange. (Good reason to buy from your LGS- shame on me). I explained the problem to S&W and they replaced the entire upper under warranty.
For warranty go through customer service at the S&W website. They pay shipping both ways through FedEx and give you tracking numbers to follow progress both ways. Return delivery is to your door, but the driver needs an adult signature. I had FedEx hold my return at their service center and picked it up from their service center. My warranty return took 4 weeks. I also sent a S&W 686 revolver in for recall once, and that recall turnaround took 10 days. I've had S&W revolvers for
25+ years. Because of my experience with S&W revolvers when I bought an AR I bought a S&W.
