I'm getting ready to recieve my bolt back from Robar after having them NP-3 coat it and was wondering about what weight firing pin spring to use , I have seen up to 30lbs but the factory is like 17lbs I think , I'm using a custom ultralite pin from Gregg Tannel thats has a steel head and shoulder with an aluminum body , all the internals of the bolt were also coated so their is gonna be minimal friction and binding.
The question is should I use a standard spring that Holland offers at about 19lbs or get a heavier spring to yet further decrease lock time
