I'm a bit out of my league here and need some advise. My instructions are to get a jewell trigger with a bottom safety, if I want a safety. I don't know enough about jewel triggers to be confident I am ordering the correct one. Model numbers are a bit confusing. I've decided I want a safety, bottom if you will, as there are times after chambering a round that shooting positions have to be changed. This is for a Bat action. Thanks in advance.
