Does anyone sell quality 20rnders with anything other than the black plastic followers ?

also, what replacement followers will work for 20rnd mags ? are they different than the ones for the 30rnd mags ?

Twenty round magazines beg the question: straight or curved.

The straights of old had an alloy follower (most believe these were the best of the lot).  New straights I have seen take a black follower.

The curved examples take the same as the thirty rounders.  I personally like the curved examples from C Products with Magpul followers when doing informal shooting.

For highpower you are pretty much restricted to the straight twenty's.  The older design with alloy followers and new springs are hard to beat.

Aluminum followers for the straight mags.
