hello, my stepfather is having problems with a single shot that i bought him for his birthday. the gun is a stevens model 9478 12 ga. the problem is that when he pulls the hammer back and squeezes the trigger sometimes it just goes click instead of boom. it does not happen all of the time and it does not seem to discriminate between brands of shells as it has done this with both winchester turkey shells and remington high brass. is there any kind of adjustment that we could possibly do to the firing pin or possibly the hammer spring? any help would be greatly appreciated.
