My pistol is still new to me, has about 800 rounds through it. Took it to the range today at lunchtime and shot 100 more. I shot the first 50-60 rounds two handed or one-handed (right) and switched to the left hand at about that point. I understand that the gun gets dirtier as it shoots more rounds but EVERY shot with my left hand resulted in the brass becoming lodged in the slide port and jamming up the works. If I switched back to two handed or right handed shooting, there were no problems at all. Maybe just coincidence in a gun that was getting dirty by sixty rounds or so or is there something mechanical in the trigger mechanism or elsewhere that causes the gun to not fully eject spent brass with maybe slight leftward trigger pressure? I'm a little embarrassed asking this because I can't imagine a mechanical reason for this phenomenon today but it did happen consistently. Thanks in advance.
