well i got the omega i was surprised with the size its smaller than i thought .but that not the issue for me i feel i really have to pull hard on head to get it to make contact to fire . i do have a flat head battery, im using AW protected 18650. ive read about using magnetic spacers but . i have the latest version of the omega , i checked the pin and when i press down on head it just barely goes past the black plastic washer, is this normal? i feel using the omega my hand gets tired or cramped from having to squeeze down hard enough to work . is there a softer sping available ? or can i tighten the inner nut to make it smaller pull ? .
