Interesting positions from people as to double or single trigger preference.
I started as a boy with an inexpensive Savage SxS 20 ga with double triggers and of course a .22 rifle with one trigger. My Dad’s Browning Superposed was one trigger……
As I got into double rifles they were typically SxS with two triggers aside from a brief time with a single trigger Browning Express in 9.3x74.
These days my only single trigger double is a SxS Sabatti in 9.3x74

I have never had issue with using one or the other. But that’s just me. Reliability of the single trigger DR? Never an issue.
Of all makers I would guess that Westley Richards has the system down pat.
