The stock Hades trigger is uncomfortable. It's too thin and tends to dig into your skin when using it. This one from OOD is dramatically more comfortable and makes the Hades much nicer to use. It's also one of the more solid 3d-printed parts I've ever handled, though I guess that should be expected from OOD. The only real negatives are that it deletes the safety, which may not even be a negative for you, and it requires sanding to really play nice with the blaster. Without sanding, the trigger has a tendency to catch and not reset after being pulled. You'll have to sand/file any edge that interacts with the blaster's body to mitigate this.
Much more comfortable design then original trigger. Easy drop in upgrade. Looks and feels great pared with upgraded Hades Pump Grip.
Be aware this trigger will not catch the safety mechanism meaning the safety will no longer work.
