School me on primer sensitivity

I have a gun (1911) that has an off-center primer strike and is not working well with some primers. Apparently some primers are easier to detonate (Federal) than others (such as CCI). 

Apparently this is also an issue for revolvers? 

Does anyone have a list of brands that are to be avoided as well as brands that are best To use with off center primer strikes?

I don't know anything about off center, but I think Federal and Winchester are considered to be the softer primers.

I've found that Servicio Adventuras primers from Argentina require an extra amount of umph when seating. There is a theory that having a primer strike slightly off center actually aids in ignition due to more primer compound being exposed to the primer anvil when struck by the firing pin or striker.

Google: "Primer Info & Chart + Milspec Primers for Semi-Autos & Other Primer Applications"

My friend who built some of my guns told me that a 1911 that has off center primer strikes is due to improper barrel fitting. All my 1911's hit in the center. The only guns I have with light strikes are my revolvers. I do have a Sig 365 that doesn't like hard primers. I only shoot Federal primers in my revolvers.
