Break it in and keep it clean. I shoot Federal red box thru mine all the time. Dad shot mine and bought himself one. Wife shot mine and i had to buy her one of her own. They are great guns. I heard the early ones had some issues, but i havent had any. Ya gotta put 500-1000 rds thru it to break it in, then just keep it clean and it will shoot just fine. Enjoy your walther!
