I have the 725 field 20 gauge what a great gun my safety is smooth no problem. I don’t Evan notice the center bead the gun shoots great I also have a 725 feather in 12 gauge love both guns .
I put a brass front bead on mine and the white center one pops better. I agree it's not necessary but I've found it useful in practice pull up and when I go turkey hunting I can make sure it's all lined up just right before I send expensive TSS.
