Cynthia, sounds like things are improving considerable and you'll just need to sort out what carry ammo it likes.
It should continue to improve and after more rounds some of those that balk now may work.
Especially early on Kahrs like a full power load. Some of those might be on the weak side. I have zero experience with Armscore, as mentioned in another thread, that's one brand I'd roll right by without looking, mostly cause I never heard of it.

Hoping things continue to get better and it becomes 100 percent reliable for you.
