I recently had one of my followers cut down to make room for one more shell.

There are some minor feeding issues once this is done but I figured out a solution.

Here is a pic of an original mag and the modded one with one shell in each. There isn't a noticeable difference.

Once the mag is loaded to capacity the last shell sits at the wrong angle (almost horizontal) and subsequently catches on the lip of the mag preventing it from feeding.

This isn't a major problem because the shell usually pops up once the mag is inserted and if it doesn't a sturdy bump will do it.

I generally use this gun in matches so I want perfection.
I then added two pieces of magnetic tape (1/8" thickness total) to the front tip of the follower to change it's angle. This has solved the problem for now. In the future when finances permit I'm going to have new followers machined out of aluminum with the new angle.

The other pros for doing this mod are....you can close the action when the mag is empty, you can easily tac load a round when the mag is empty and the last round no longer stove pipes. :runaway:
 
In your second photo, your modded follower on the right, isn't it supposed to be pushed all the way by the spring?

Does the follower flop around in the mag tube between the spring and the lips now?

No.

Look closely at the first and third pic. The first pic shows the notches at the base of the follower. The third pic shows where they rest (indents in the side of the mag). The follower is being forced against the indents by the spring to keep it from wobbling around.
 
I understand completely now.

How tight is that last shell held in between the top of the follower and the lips? If it's tight and the flaps at the bottom of your follower were cut on the same level as the original follower, why would that last shell be at a different angle now? You shouldn't need to add any material to the top of the follower to feed properly.

Could it be that your spring is installed flopped? Just a crazy thought. :)

I think that's a good mod. I think you have yourself a winner.

I left a little room so it's the same tension as original.

I believe it's the curvature of the mag frame or lack thereof? It seems that 5 shells is perfect and the sixth is the breaking point. If the mag was curved slightly more I think the problem would not exist. Kinda like the 7.62 AR feeding problem.

Thanks!
 
Then you'll have no choice but to reposition those little flaps so the follower sits at the desired angle. Maybe one degree would do it. Simple fix. Is that what you were thinking of? :)
