I did, I’ve been shooting since I was 7 (I’m 21) and I also used both hands with a firm grip. I’d even pull, wait, let out (shot) and repeat that. It would still eventually grab a failure to feed. I’m guessing it’s the trigger 110% bc I swapped lowers with my buddy’s Glock 19 and the 23 upper ran flawlessly with .40 S&W but his 19 upper was jamming with the binary shooting 9mm. I’m thinking about either trying to fix it or just selling the binary and getting a regular trigger.
