If you want to compare? Right-click on the model and open it in a new window. Then click the tool-bar tabs for side-by-side comparison.
The 360 view slider is nice too when making comparisons.
P.S. the wt. difference RE: the G23/G19 is 0.32 oz on the Gen4, same/same on the Gen3... could be anything or a whole bunch of even smaller things. Loaded wt. is an aggregate of round ct. and bullet wt. Don't know what they use.

Here is the other site: http://www.glock.com/english/index_pistols.htm
