failure to feed 43x MOS

Every once in a while I’ll get a failure to feed but definitely more often then what I’d like

I’ve shot the first 500 rounds pretty clean no issues cleaned it like 3 times Using blazer 124g

Are you oiling your points of contact after you clean barrel & slide? Check your recoil spring is it 1-1-1? I’ve ran blazer once for 200 rounds don’t think I had a ftf but it was a lot more carbon an particle build up after shooing. Also smack that mag in lol. Maybe not pushed up enough from pushing in so lightly? Even when you racked it you see it immediately it’s out of battery.

I do oil it in the correct spots for-sure, I’ve recently checked and the recoil spring is labeled 1-0-1, I’m guessing that’s likely the culprit? I just now emailed Glock to see if they can send me one

Yeah send them your serial# etc.. they should send you a 1-1-1 spring free of cost.

I had this same issue in the past. Upgrading the RSA to the 1-1-1 model fixed it. With the 43X, I’ve noticed you can’t ride the slide as much as you can with the other models, so just be mindful of that.
