Mini 14 1911 buffers & xtra power recoil spring Pros & Cons
as the topic says i'm a little bit confused on the pros & cons of
1. 1911 wilson combat buffers
2. wolff xtra power recoil spring
in a mini 14
i see both sides and in the net users state the one or the other side.
i suppose the purpose is to increase gun life time, by minimizing the impact of the slide assembly on the receiver (on its backwards motion) and gas block (on its forward motion)
i, more or less, understand the purpose of the 1911 buffers, but not of the xtra power recoil spring.
if the factory spring is too weak it must have been fully compressed and the slide assembly would still have power to move further back, otherwise it would be strong enough.
it can't be connected with the volume of gas left in the system after firing either, because of the holes in the slide assembly and the opening of the gasport after the backwards motion of the slide assembly begins, all the gas left will expand in the stock, not in the slide assembly any more and therefore the xtra power spring will not save the slide assembly from gas overpressure/force and speed, because there is not more gas left, than with the weak factory spring, or am i getting something wrong here?
please help me to understand why some people recommend buffers and xtra power spring ( or just the one and not the other) and some dismiss these "improvements"
