So, for some of us, our vote has more to do with which firearms we already own rather than what we believe about minimum capacity? And if we owned a two-shot Derringer our vote for minimum capacity would be two?
Interesting observation.
In my case, I only buy revolvers and pistols which have "standard" capacities which I find acceptable for their intended roles (which has typically been as either off-duty or retirement CCW weapons).
This means I accept the inherent 5 & 6-rd revolver capacities ... and the 6, 7, 8, 9, 10 & 12-rd pistol magazine capacities ... as acceptable for the various roles for which I bought them.
If I were still active full-time, I'd carry the same 7+1 rd compact .45 I was carrying at the time of my retirement ... or, I'd not be averse to again carrying a 6-shot medium frame revolver. I could see a little advantage to carrying one of the large frame Scandium aluminum 8-shot revolvers, though. Lighter on the hip, and the extra couple of rounds puts it up in the same "capacity range" as the 7+1 .45 pistol.
I really liked the issued 6906's I carried for several years, though, and their 12+1 capacity made it easier to run through the longer qual courses-of-fire without reloading.
All of that said, while I'm presently driving/traveling out-of-state, I brought one of my 5-shot J's and my LCP as LEOSA weapons (the LCP for those times when it slips into a pocket holster in some jeans better than the J-frame). I remember the days when I used to carry my 3913 (8+1), or a G26 or G27 during my out-of-state driving trips.
