[QUOTE=canebrake;968434]This is one of the many reasons I use Tripp Research mags.
The follower is a critical component in the safe operation of your 1911. When the mag is empty the follower contacts the slide stop and locks it back to signal the shooter the gun is empty.
Many of today’s magazine manufacturers use an all-poly follower which interfaces with the metal slide stop. Yes they wear and yes they fail to lock-back the slide and in a PD situation, have the shooter pulling the trigger on an empty gun.
Here you can see the Wilson ETM mag on the top with a poly-follower. (Note the witness mark where it contacts the slide stop.)
The bottom is a Tripp Research Gen II Cobra mag with their hybrid follower.

Call Aaron @ Tripp (877.837.9445) and talk to him, he'll explain what's available and get you fixed-up with what you need. (Tell him canebrake said hi.)
I bought a pair of Tripp Cobras to run in my RIA tactical 9mm. The follower in the Tripps has the same patent number on it, 6,560,907, as the one that is in the stock mag. The Tripp mags do load easier than the stock mag.
My Tripp 45 mags have the hybrid follower. Maybe Tripp just chose not to develop a 9mm hybrid follower.
