Overtravel trigger screw won't budge

Hi everyone, I have two handguns with an overtravel trigger screw: a CZ Shadow 2 SAO (with a modified trigger) and a Phoenix Drake Standard. I’d like to adjust the overtravel screw on both, but I can’t seem to figure out how to do it. From what I’ve read, they’re usually set with red Loctite, which means they need to be heated to loosen. I first tried using a butane lighter, but it didn’t help. Today I bought a small soldering iron that heats up to around 968°F (520°C) and applied it directly to the screw for 10 minutes, then 1 hour but it still wouldn’t budge. At this point, I’m not sure what else to try. Has anyone here run into the same issue with an overtravel screw?
