I can adjust everything but the magnet tension fine.

The adjustment screw seems to be stripped by the previous owner, a 1/16 allen key can fit inside the hole and spin almost freely. The screw refuses to come out, I've tried using needle-nosed pliers but with no success.

Am I stuck with a super low magnet tension...?

Is the tip of the screw level, or above the surface of the trigger? If so, your trigger pull is already as strong as it can be. With the tip of the screw in contact with the frame, it is already as close to the magnet in the frame as it can be - all that turning the screw in further will do at that point is act as a front trigger stop, tilting the trigger back.

Fact is that the magnet in the frame is small, and not very strong, so only gives a weak return force anyway.

Some people remove the stock magnet and fit a larger or stronger one. Some people remove a little of the frame material under the magnet, so that with the screw extended passed the surface if the trigger, the screw can get closer to the magnet.

The problem isn't with the tension.

What I'm really worried about right now is the fact that I can't turn the screw.

OK, dealing with that, funnily enough brings me to asking the same question. Is the tip of the screw protruding passed the surface of the trigger? If so, you could remove the trigger and then use a rotary tool (a Dremel or similar) to cut a slot in to the tip of the trigger, so that you could then use a screwdriver to remove the screw.

if the screw is long enough take a small wrench to it

I've tried using pliers and wretches but nothing seems to work, it refuses to move.

How can I drill a hole into the trigger without damaging it?
