I don't know, Steve...
The question was "which is more popular".
Not "Which have been more produced".
I don't think it's that simple to just look up "How many autos have been produced", or any other kind of similar blanket statistic. I don't even think, for example, we could accurately look up how many different companies have built 1911s or 38sp revolvers. And for those that we could look up, we may not be able to get any kind of figures.
And "popularity" suggests "what's in use now". And to a secondary point, esp in this kind of forum, I think it suggests "Why", Suppose there's a lot of auto owners with guns on their shelves or in their safes while there's a lot of revolver owners going to the range every week and actually firing them. Or suppose there's a lot of police agencies carrying autos daily but firing them only at quals every 6 or 12 months. Or suppose that six guys shooting revolvers at the range fire a total of 300 rounds one day, while one guy with a Glock fires 600 rounds the same day. I think it's a little difficult to say that one is more popular than the other when you consider that some of them aren't getting fired, some are buried in the prepper vault in the back yard, some are getting fired once a week at the SASS meets and matches.
I think all of those qualifiers like "in my household" and similar are valid and most importantly interesting to read about in a discussion forum. I'm interested in hearing why others like this or that gun. I'm not looking for emperical statistics on how many have been manufactured.
