If you take a close look at a double trigger gun, the rear trigger is set to the right (or left dependant on the hand of the gun). This is to allow a natural 'flow' of the trigger finger to the rear trigger. This is why just the tip or pad of the trigger finger is used and NOT the first joint. Having said that, I usually pull the rear trigger first (choke barrel) and then move to the front trigger (open barrel). They are easy to use and I use them without thinking. Like I never get caught with the auto safety on a game gun, BUT I have been known to get caught with an auto safe on on a gun used for clays. When using one of my auto's for clays, the safe goes off as soon as the gun leaves my cabinet, when being used for pigeons the safety stays on. It is just a simple matter of knowing your gun and what it is being used for. I cringe when I see game shooters load and push the safe off whilst awaiting a shot. The safe should only be pushed off as the gun is being mounted into the shoulder, by then it is clear of buttons and things that can catch the trigger during gun mount. The double trigger has some major advantages over the single trigger. Some guns and especially older English guns had unreliable single triggers which were also non selective, if one barrel fails on a double trigger gun, you have at least one barrel which will still work, or that was the plan. Remember a lot of old English guns saw service in 'the Colonies' where gunsmithing was not at it's best, so a good old robust double trigger gun was sought after. Westley Richards made (and still do) a 'droplock' to Americanise it, which had removable locks. Should a problem occur a spare lock was fitted and the broken lock sent home for repair. (Perazzi owners note !) When using a double trigger and straight hand stock, the grip is not altered, but it is more natural for the finger to drop back. Trust me it is less likely to have 'trigger freeze' with a double trigger gun, nor do you have to rely on fully releasing the first trigger to fire the second barrel, just drop the finger back it really is so easy.
