I've not seen that feature on a SxS, Jack;-) Replace bottom for right and top for left & we are back on the same page for Supers, I think.

I once made the statement here that all double triggered Browning Supers were double singles. I was quickly taken to task. Kensal obviously has one of those that is not.

Both of the ones I have are double singles. Both guns' triggers function fine as single inertia triggers with loads as light as 24grams @ 1050 fps. I've never tried lighter loads like the Winchester Feather-lites in either gun.

One of them is a Mod/Mod. Not sure what the original owner had in mind, but if I had to guess he wanted a Mod choke, irrespective of what his brain was doing when he pulled the trigger.
