recently purchased a hi power DOM 1975. have found it misfires about 20% of the time. the misfires have a very light primer strike, the rounds that fire appear normal. pistol is clean and lubricated properly. at times it has taken three to four tries to get the round to fire. have only used one type of ammunition so far, Blaser Brass 115 gr. will try some other ammo as soon as i can get some. any ideas other than that? DOM 1975

Check that FP channel is clean and lubed. Check that FP and FP spring are not damaged.
Maybe you should be looking at the firing pin spring also.
Complete Wolf spring kit replacement set for the BHP.
I'd start there, FIRST !
I would bet some bubba did a "trigger" job and cut a few coils off the hammer spring or replaced it with one that was to light.
get a small wooden dowel about 10-12" long and put it into the barrel with the pistol pointing up and pull the trigger. If the firing pin is working correctly it should shoot the dowel almost out of the barrel.
A BIC pen and/or a Ticonderoga #2 will do the same thing and might be easier to locate

Since it seems you may be taking apart and reassembling your BHP, one trick I use to cut down on swearing & aggravation putting it back together is using a plastic loop to hold the hammer at full cock - one end holding back the hammer and the other hooked into the open magwell. Whether you're using a vise or not, leaves your two hands free for manipulating the sear, ejector and pins.
I had an issue with an HP where a piece of a primer was lodged in the firing pin hole and kept the firing pin from consistently making full contact with the primer.
Good point. I had the same issue with a SA EMP in 9mm. Was difficult to determine because after the misfire another pull would dislodge the bit of primer and all would go well. And it happened with only certain ammo brands, stouter stuff IIRC.
