P99 Lockup

My new P99 locked up at the range today. I was using Brown Bear 115 gr. FMJs. I ran two mags full of the same stuff thru my Kahr PM9 with no problems. Since the gun locked up with a live round in the chamber, I took it directly to a 'smith. Then I called S&W ( Smith & Walther). They will send me a shipping tag so that when the gun is defused I can send it to them. I hope it isn't a problem with the gun. I like the P99. I'll keep the board posted on the results.
