I did a search and only turned up 4 threads on the subject. They really didn't answer any of my questions. Here's what I've got: Wilson Border Patrol 12 Ga. 6+1 870 Express (And no, I didn't spend thousands of dollars on it. I got it when they were still in the 800 dollar range. Awesome shotgun!) I am doing a couple of upgrades to it right now. So far: Remington 870 Police Trigger Assembly group (Got a thread about that too) Speed Feed "Short LOP" stock TacStart Side Saddle Upgrading to Wolff Tube Springs What I would like are some Pros and Cons of the metal style followers vs. the synthetic followers. Currently I have the Wilson style synthetic follower. I haven't had any problems with it. However, if a metal follower is a better upgrade, I would like to start using them. Pros to Steel/Cons to Steel Pros to Aluminum/Cons to Aluminum Pros to Synthetic/Cons to Synthetic I appreciate the help!
