I used an extended firing pin as a sponsor sent me one with a bunch of other parts, took it out after finding it didn't make any difference and at the time it not being legal to use in competition. Never bothered with one after that. I think they are a waste of money. Super light firing pin spring, yes. I just stay at 10lb for main spring and it lights off everything, Ginex, CCI, Federal, S&B, Fiocchi, Armscor, Remington, Winchester, I've never had an issue with a regular firing pin. I used to run an 8lb main and did suffer the odd light strike, same with 9lb with some of my practice ammo, so I just went with a 10lb and stayed there. The extended firing pin didn't help, only spring weight did.
