The gen 4 spring is a dual sping-inside-a-spring setup and it cocks visible stiffer.
The glock rep told me they last much much longer than the old ones, which didn't seem that bad to me.
It seems some people that load or load lighter get stoppages with this that they didn't with thier older models.
Like you, I will shoot mosltly factory or load to the same specs.
I've seen that with 1911's and WIN CLEAN. Anyone try that in a Gen 4?
