Another +1 for the Apex kit.

Installed it after the first to mags all other ammo has been fired with all 3 apex springs with nary a problem. So far I have gone through
Winchester white box
Privi Partizan
Remington golden saber
Hornady Critical duty
Winchester PDX
I also have 100 rounds of Tula I am gonna try but to be honest I don't want to shoot it with all this crazy stuff going on as I may not be able to replace it.
