Hi everyone, thanks for welcoming me to your forum. I'm 65 and live in NC. Retired from government after 34 years, as C, Project Br. Mgr. I purchased a 9mm P95DC new around six years ago and have never fired a round through it. But since the world is rapidly changing around us and getting worse, decided to get familiar with it, and especially to train my wife. I'm somewhat familiar with guns since I've had a Blackhawk Super Single Six for about 35 years, but not familiar with grain. I decided to pick up practice rounds and take my wife to pistol range to finally shoot it. While I was at gun shop also purchased Remington 9mm Luger (Subsonic RTP9MM8) 147 gr JHP. After reading thread posted about a 147 gr not discharging from firing chamber and having to update the gun, am I going to have any of the same problems? I also noticed that on side of barrel where the shells discharge, it has scribed on it, 9mm x 19.
