Ok, I tweaked the lifter down slightly. You can barely see the bend, but I didn't want to go any farther. With the guide on the right side of the lifter, any more would have made the lifter start twisting. I test fired it and shot 25 rounds without a jam. I still need to run some more rounds through it, but originally it would jam within 15 rounds, and after putting in the Glock springs it wouldn't run 8 rounds. So, it's a least an improvement.
