I'm not here to sign the praises of one type of follower or the other however I would like to know if they are a gimmick or prevent a problem. I personally view them as being like a full length guide rod or an ambi slide release on a .45 Auto. Where is the magazine spring going to go if you use a non-tailed follower? There's no place for it to turn into a Slinky, that I can see. Does the follower material matter? I need a pro opinion on this.
