MBSR,
You didn't state the kind of SxS you are considering & it's intended purpose(s).
I think the more important issue is that whichever type trigger you choose that it have decent 'pulls' and minimal creep. Some guns, even expensive ones can have less than good pulls [triggers]. A decent gunsmith can usually remedy either type, if it is an issue, but it becomes an added cost item.
Another factor is whether or not you intend to use it in cold weather; not everyone is comfortable with Ted's solution to shooting bare handed in cold weather, so it may or may not matter if you can get a gloved finger onto the trigger or triggers easily. It is certainly something to think about, if it matters.
I cannot tell the dif. really, having both, but will say the arguement for double triggers is more just that, today. Was a time past when there was perhaps no such thing as a reliable single trigger and plenty has been written about it, but there must have been demand even then, otherwise..?
Today, most any reputable maker has a single trigger that is both effective & reliable. That is evidenced by a myriad of competition shooters using nothing but. There may be some top competitive shooter in some descipline using a double triggered gun, but I have yet to hear of them. A small gauge gun will normally benefit from a mechanical single trigger rather than an inertia design because of the reduced recoil.
Its a matter of your own taste. Double triggers are not difficult to use, but if you are going to be shooting heavy loads and/or have thick fingers, you may benefit from having the front trigger 'articulated', meaning hinged so that it swings forward when/if your finger slaps it from the back side. Some folks get their finger bruised shooting double triggered guns when using the rear trigger. Depends on a combination of the shooter's build and the gun's.
kind regards. tw
