For years I passed on buying the Glock 20, due to the too-large grip. I could reach the trigger but always felt it was just the opposite of ergonomic.
Not long ago I first saw a 20 Short Frame (SF) version. Bought it right away. The changes just made all the difference to me. So this is my advice - buy one!
Now I have to get some of that real-deal full power 10mm ammo, for the shooting adventure of firing hotter loads.
