I have said this as well,
single stack into production 8 round major 10 round minor
let production gun stick magwells on there.
or production should go 15 rounds
limited 10 should go away
+1 to most of this.
I'm not crazy about the magwell idea. I'd go the other way. Limit SSTK guns to magwells that don't flare beyond the grip profile. E.g. the S&A style.
