SRY - have heard of them - thought they were usually accompanied by replacing the stock spring with a stronger firing pin spring, as in a 26# to 28# Wolf Spring.
The Titanium firing pin is lighter, therefore does not have the same Kinetic force on the primer. A higher pressure spring, that is, higher than the standard 22# spring is usually desired - decreases lock time & jar of the pin hitting the primer as well.
I do not know what the exact metalurgy is or where they might be available.
Since you hail from the States, try Brownell's.
