Seems the forum almost demands these pics. Way too many threads revolve around the choice of the compact vs sub-compact Glocks as a choice for carry these days. Here are some pics to help those on the edge decide. The actual difference in the length of the grip with stock magazines is only 3/4" for the G19/26 or G23/27. Virtually no difference if one has the finger groove +1 extension on the subs. Last pic is one that says I love my Glocks.........you can actually see the heart!

By the way....anyone can tell both of these Glocks do not have a loaded chamber just by looking. The triggers are in the rearward position. The way I store all of my unloaded Glocks whether they have a full magazine inserted or not.
