Hey buddy great question.
I think for a gun that we may very well sit on for extended periods of time, the small flat mouse guns work better.
I think the little auto pistols are also more easily masked by things like checkbooks, passports, and larger wallets. I haven't even touched on doing that yet. Masked, preemptive draws. Think about getting a tiny pistol out in a supermarket check-out line surreptitiously and preemptively. Why would you want tp do that? I don't know. But I like the capability.
I think also for an actual two gun system that people could carry literally in beach shorts and a t-shirt, something like a Sig 365 set-up for a fast appendix draw and a Keltec P32 set up as a PCP would be something that's not obtrusive and livable.
