Colt Revolver's name in the English version is SAA. These aliases will be helpful to those who are unaware of the difference in name.

Should it be the other way around if the English version is SAA? I don't know which standard GFL goes with on here.

In terms of tag names, we currently lean towards CN (so we have HK416 as opposed to just 416, G11 as opposed to Gr G11, Type 100 as opposed to 100 Shiki, etc.), a decision made back during the big Apostrophe tag update. EN names consist of a mix of accurate names (aligning with CN), slightly fudged names (to avoid copyright issues, ala the use of Gr on select H&K guns), or completely fudged names for understandable reasons ('Type XXX' is used for Chinese guns, so they had to use 'XXX Shiki' for Japanese guns, as one example).
