I've taken an OCD approach to my ammo and triple checking it to eliminate any chance of malfunction.
WHY .... now ?
Because of primer strikes that my son inlaw an army armored says should of gone off.
As reloaders we all have experienced hits that should of gone off, but during a stage it makes for a bad run. It's not uncommon for a 1911 to experience it and common reasons as high primers or other variables.
With a striker fired gun there are a lot more various causes for it. I have not polished any of my Apex parts only shot the gun.
There are about 2k shot since I went with my setup, and since I went OCD on ammo the light strikes have gone 99.9% away.. so I guess any now are primer Mfg related.
(And any sear flutter was cured with a heavier sear spring early on.)
My trigger started at 1lb 12oz, last nite after cleaning and checking pull weight afterwards it has dropped to an average of 10 pulls to 1lb 9oz. With a low of 1lb 7oz.
