I bought the Enhanced Competition Follower and once installed. It will not allow my Mossberg 930 SPX purchased new in Oct 2019 to accept 7 rounds. I can put in 6 rounds and if I try 7 the magazine tube is very tight and double feeds the first two rounds causing a jam. The only way I can it to work is when I remove the white plastic magazine tube spring retainer. I called Mossberg and they said the gun would not function/feed properly without this part. Is your Or3Gun follower not designed for the 930 SPX? Attached photo is the part I am referring to that will not allow the Or3gun competition follower to work but Mossberg Tech Support states i required to function properly.
