I figured it out so just wanna share with my experience here. The first time when I tried to remove the screw, I didn't know it was loctited. I stripped it. After stripping it I tried different kinds of extractors, drilling, etc, and I ended up with completely messed up the mag release. So I bought an OEM mag release for $35 and started over. This time I used a heat gun and a good T10 screw driver that fit very well with the screw. Wiggle your screw driver over the screw and feel how much free space there is. I originally used an Amazon Basic screw driver set and I also tried Amartisan screw drivers set. Both are bad. In the end I found that Wheeler gunsmithing screwdriver set fit the screw very well. Very little wiggle room. So, use the heat gun and heat the mag release for 2-3 mins, and then WHILE HEATING IT, use the T10 size driver head to slowly turn. Apply good amount of pressure downward so that the teeth are tightly engaged. The screw actually came out with little effort. Don't stop heating the mag release or let it cool down. With high temperature the loctite inside turns very soft. If you let it cool down, it could go back to the super glued state. That's pretty much it. Keep heating it and use the screw driver brand that fits with the screw very tightly. Good luck folks.
