I am wanting for someone to tell me why pulling the rear trigger second is the correct way of doing things.

If single triggers are good enough for Westley Richards and was good enough for Jimmy Sutherland it is good enough for me.

I don't see how it matters really to anyone what trigger the hunter pulls first. Do whatever you want.

I know it is tradition but I also fail to see the need for two triggers to begin with. I have yet to hear an actual big game experience where a tourist hunter went about only shooting one barrel because the other trigger mechanism failed.

So much of what is available in the retail, new double market today is accepted as the standard because that is what is available. For example, it seems that many manufacturers, but not all, are making barrels to fit their existing receivers regardless of the caliber. A 450/400 gets made on a 600 NE frame. A 470 NE barrel has the same profile as a 500 NE and the 470 winds up weighing more than the 500! Try to justify that one. I had a rep of one of the European maufacturers, which make exquisite doubles, at the SCI Reno show refuse to even talk to me about a single trigger.

Of course I have my own prejudices such as single triggers, lightweight, ejectors, and all that.

Do whatever you think is best.
