My friend… you are talking about mall commandos yet you are the one with the 44 mag sunb for defense… and the 50 “Special”..
There’s nothing commandoish ( just invented that one) about Glocks or Hi Powers, just to mention a couple of the guns that came to mind when I said that you could have 15+1 rounds or more for almost the same size.
As Nemoaz suggested, if you bother enough to carry, carry something that offers good firepower, but if 5 shooters is your thing, go for it.
I think that your autos are much better defensive tools. Offer more peace of mind if you ever happen to need to defend yourself from more than two attackers.
The weapon on the pic is real enough, also very nice piece, but you can get something that has 3 times more capacity, it’s less bulky (personally, bulk bothers me more than weight) and fires a more powerful round than 44 special..
Since you like 10mm, a Glock 10mm, for example, would fit such description.
