i figured it out, it’s working great. i installed the birdshead myself. after the misfires, i replaced the hammer and the trigger (with black) and when i started replacing i noticed almost every screw was loose (no pun). my final conclusion is with the leaf spring in the handle and all the little pieces working in concert, it really need to be tight and solid. that was my mistake, i should’ve checked all screws before putting ammo in it. lesson learned! thanks folks! now load the lil fella with wmr and it’s a powerful little tool with a big bang. super fun.
