Re: Titanium fire pin does it help?
The things I've read have touted shorter lock time, and reduced risk of slam fires.
I have not used one, basic physics indicates they probably do decrease locktime, which is one of those things that probably won't make much difference most shooters. I've had allot of dimpled primers of varying degrees, in fact every one I've ever ejected that an AR chambered, but I've never had a slam fire, so I'm not worried about reducing the risk.
I would worry about mis-fires from the pin not having enough mass, atleast until I ran it long enough without any.
