Here's some shots for anyone who wants to try this themselves.

You'll need a precision screwdriver with a slot tip to pop the metal upper portion of the magazine off the plastic base.





You'll slip the tip of the screwdriver right here at the side of the plastic base where it curves up. The plastic lug that engages into the side of the magazine metal upper is located here.




Push down gently, release the lug and the metal will pop up.




Flip it around and do the same on the other side.




Take a small piece of paper towel wetted with rubbing alcohol and wipe down the face of the plastic block at the rear to ensure the tape adheres well. Let this dry. Cut two strips of 3M 2242 tape ~5/16" to 3/8" wide & a little longer than the plastic block. Going from the underside of the upper metal piece (there's more clearance going from underneath), stick down the first piece, ensuring the top of the piece is flush with the top of the block, then trim to length at the bottom. Stick the second piece down over top of the first & trim to length.

Cut a piece of Low Friction Tape ~5/16" to 3/8" wide, remove the backing and adhere over top of the 3M tape. Ensure the top is flush with the top of the plastic block and the two pieces of 3M tape. You don't want anything sticking up out of the top of the magazine.

View from the bottom (the layers of tape don't have to be perfectly placed or ultra photogenic, they just needs to be stuck down and close in width):

At this point if you'd like, you can stretch the spring out a little to make it more crisply push the follower up.

To reassemble, slip the follower and spring into the upper part (it only goes in one way), orient the plastic base and metal upper part correctly (it will be obvious when you look at this). Slide the rear of the metal upper part onto the lug on the plastic base, engaging the lug into the hole in the bottom of the metal upper part. Then, using the screwdriver, engage the lug on one side and then the other into their slots in the metal upper.

Take some dummy rounds and test. I think you'll find it works much better now.

One caveat is that you'll lose a little mag length with this method - around 1/16". I didn't find it overly impactful however & had plenty of room, even with a load with a reasonably long OAL.
