I want to share something with you guys. I was having problems with my 32 round Colt 9mm mag. The 10 round Duramag mag ran fine, but the 32 round ASC mag caused FTF issues. Found out why. Look at the pics below. I have a KAK magwell insert on the table and the two mags (I ended up getting a Hahn Precision insert instead). They mags appear to have identical followers. But the slot for the mag release is cut higher on the 32 round ASC. If you look at each mag inserted in the magwell insert, the ASC sits a little higher. This causes the following chain of events:
1. In order to seat the 32 round mag, you have to bang it on the table.
2. When you do that, the magwell slips upward.
3. This causes the mag release to bind.
4. But worse, the mag sits too high and feeding is unreliable at best.
The 10 round mag runs fine. Interestingly enough, the 32 round mag seems to run in the CMMG Banshee clone I built, but the 10 rounder is easier to insert.
