There is one problem I have with my glock. If I shoot it resting one handed, or just shoot it weak handed with a unconventional grip and arm position, it will mis-feed. Now I know this is something in which all auto's suffer from...but it seems like you need to shoot the Glock with a firm double handed grasp every time. I like to tactically shoot from unconventional positions, such as lifes situations. Has anyone else had this problem? It happens to my 19C with my 115 gr practice ammo and my 147 gr duty ammo. Are there corrections?
