I already have an Apex pin installed in my 66-7.

I tried installing the Wolf Type 1 spring kit (or whichever one is “duty” rated.)

I like the trigger pull, but it is not completely reliable with magnum primers. About 17% fail to ignite when shooting double action, even after double-seating the primers. This holds true with factory magnums as well.

Is there a firing pin that’s maybe a hairs-breadth longer than the Apex?
