Grizzly Win Mag Pistol Barrel Porting

The following is a letter included with a Grizzly .45 Win Mag Pistol with a 6.5 inch Barrel I own . I'II enter it exactly as its written -----------------------NOTICE --------------------------Dear Customer , Please note that the Barrel on your Grizzly Win Mag Pistol has not been ported. After substantial testing , we have found that the ports hampered accuracy and velocity. Also , the test revealed that the recoil with or without the ports were not that noticeable. Accuracy and Velocity far out weigh the recoil advanatge prompting us to eliminate the ports. Thank You, L.A.R. Manufacturing Inc.
