Why a SST on a double gun?

Kenny, according to W.W. Greener (The Gun and Its Development), the single trigger on a "double-barrelled" gun appeared at least as early as the late 17th century. Greener stated "the single trigger undoubtedly possesses advantages over the two-trigger gun, principally the facility with which two barrels can be fired in rapid succession; the same length of stock is secured (LOP)-with most mechanisms- for both barrels, and there is no necessity to relax the grip of the stock. What these advantages mean to the sportsman can only be fully appreciated by a fair trial at game."

For gun manufacturers the choice was simple, the competition had them, people wanted them and were willing to pay.

This is a great thread. I agree with just about all the posters and particularly with Todd. I too feel that SK or Cyl and Mod or Full are just about the perfect combo for a field or target gun. Shooters in the early 20th century must have also felt this way as there are a lot of guns choked open/tight. I love double triggers for their dependability. When I was younger I sought out single trigger Parkers because that's what I was used to. Now, I know that DT guns were the choice of many, many shooters of that era. Must have been a good reason for that.

They go "off" every time you pull one of the triggers. The single trigger, not always.

Bill, you must be talking about properly cocked hammer guns. I cannot remember the last sxs shoot I was at where I did not see a target launched, and some shooter with a double trigger hammerless gun swing on it, pull on the trigger and when nothing happens say something about the "damn safety". I am often one of them. Most reliable shotgun: single barrel hand cannon with large touch hole and kerosene torch. Every device added after that increased the probability of mechanical and/or operator failure.
