I grabbed a 5inch Pro series 9mm today. it is just an awesome pistol. Light trigger great high viz front sight. Greta grip. I took it to the range out of the box and had 200 115 grain Wichester white box rounds. On round about 160 i had a failure to extract and a feed on top of it. I am hoping it was just a round out of spec or a fluke. rest of the ammo sailed thru it. what could have caused this?? is it mag related. Extractor and ejector looks fine. I do not want to return this pistol.
