I wish I knew for sure, but my 7TS doesn't seem to have a specific 4-digit part number stamped on it like the older 6-series holsters do, and I no longer have the original packaging. The back of the holster is only labeled "Beretta 92F, FS." I've owned this particular 7TS before the Brig Tac was a thing, so when I ordered it, it would have been with a standard M9 in mind.
If you go to the Holster Finder on the Safariland web site, and select "92FS Brigadier" you will get some 7TS options. IIRC, at some point I noticed that those 7TS catalog numbers matched the output for non-Brig models. That observation was what led me to try the Brig Tac again. Given the limited numbers of Brigs and SD's in duty use now, I don't think Safariland would have gone to the expense of making a special mold for the Brig slide guns.
FWIW, I typed "92A1" into the holster finder just now, and didn't get any 7TS options, only some GLS configurations and a leather pancake.

If you have a 7TS that works with a 92A1, I'd like to know more.
