So, I dropped my Omega a while ago and the threading got messed up a bit. The carto that was screwed in got pushed to a weird angle and wouldn't unscrew. After I got it straight, the carto came out, but now the Omega's threading is screwed up a bit. Certain 510 cartos won't screw in, and others are loose enough to tilt slightly to the left or the right. Does anyone know if replacement switches are available? I'm also curious, do the Silver Bullet switches screw on to the Omega battery tube, or are they different measurements?
