How much does a pistol have to weigh (loaded) before you consider it heavy? This is of course a subjective determination unless we analyze the spectrum of pistol weights and find an average. I really hope we don't do that, but if anyone else does be my guest. Think about what weight in ounces you find heavy for CCW in various carry modes, and what you consider heavy for belt holster carry. I'll start first with CCW in a pocket: anything over 16oz is getting heavy and over 20oz is too heavy.
