Default 4006 Mags

I have noticed yellow and blue followers on the 4006 11 round mags. Is there any difference? One upgraded version or just color change?

Thanks,

Rosewood

All I have noticed is the size/shape of the dimple at the bottom of the mag.

There was quite a thread on the Model 4006 and it's magazines a couple of years ago. I tried to find it, but my google-foo isn't working at the moment.
edit to add: Found the thread at the link:
4006 mag follower color

Yellow are early followers. Blue the later and current follower. Other than color I can’t readily identify a difference.

My google-fu wasn't working either and I figured if I asked the question someone could/would direct me to where it had been discussed before.

Thanks!

Your welcome. I directed my last post to member surfgun. I'm surprised that a couple of 4006 magazine enthusiasts haven't chimed in yet....

Default Wow ........I just read all the posts

Wow........I just read all the posts going back years and I am still confused. the whole yellow are pre ban(maybe?) and blue are new.(and look great in the plastic S&W blue boxes) theories were interesting.

I have had conversations on Ruger forums about the exact problem with their mags. Ruger had 40 cal. P series 11 round mags. That ended in 1994 when they dimpled the mags to accept 10 rounds. Problem is some of the 11 round mags look dimpled and some do not making it very hard to tell what you are getting. I have purhased some 10 round mags on Ebay and to my surprise, I ended up with 11 round pre bans.

I gathered the blue one was an "accuglide". Much like the 10mm went from the yellow to the white "accuglide" follower.

I once asked during an armorer class what changes were involved in the transition from yellow to light blue .40 3rd gen double stack followers. Neither the instructor, nor any LE service/parts people I called later, could tell me why the color had changed or if there had been any other specific revisions.

One factory guy offered an observation that sometimes when the factory changed vendors of a part, or an existing vendor made a minor change in some internal spec (plastic formula used), the color would change denoting the change. He said that not all color changes of things like plastic parts (or springs) necessarily indicated an actual design change or engineering revision of the part.

The light blue .40 double stack followers are the most current. I was told that S&W sometimes sent replacement revised .40 followers to LE agency customers, if only because they requested it when they learned of the change, and it made them feel better. Maybe so. Wouldn't surprise me.

Sometimes it did indicate a needed design change, though. Always best to ask the company.

For example, when the SW9940 followers changed from dark orange to light orange, it was due to a subtle revision of the follower shape, necessitated by the mag body receiving a change in shape adjacent to the mag catch window. The added "flat" in the mag body resulted in the left side of the follower being molded with a 'relief' clearance spot to accommodate the change in mag body shape. The P9940 followers received a similar color and shape revision, for the same reason (going to a lighter blue color for the revised .40 followers, if I remember right).

If your concern is obtaining the most reliable follower don't sweat it, they both work.
