----------------------
I find up to 20-22 oz pretty light, with a holster, no feeling of 'lugable'. G42 meets this requirement
*(Luggable was the term for an old Compac portable computer in the 1985 era, meaning somewhat annoying to lug around)
G43 appears to be 8 additional oz over my perceived informal 'limit', total carry package. (not including spare mags)
