I have about 600~ rounds of tulammo through my first p-09. It has the cgw extended firing pin and spring but stock main spring. Never had 1 hiccup. Have another 09 with probably another 150 -200 rounds of tulammo, stock main spring but just added cgw firing pin and spring, maybe 100 rounds of tula with that.
I love tula for cheap range fodder. I don't reload, so I order that stuff by the case. My experience with it has been MUCH better than the few cases of freedom I ran through a few years ago. I will say, getting serious about shooting for groups in the last few months - I go to better, brass cased stuff for that (lawman or sellior bellot).
