i know that a longer barrel usually gains velocity and power but does anyone have any data on specific loads in a standard glock 20 vs a 20L? i currently own a glock 17, 26, and 35. looking to buy a 20 soon, possibly. looking to either go threaded barrel and a carver comp, or a 6" lone wolf upper but am curious about the gain. my uses will be primarily a woods gun with the probablility of handgun hunting whitetails in TN. thanks ahead of time.
