I guess the only upswing of knowing you could fire .40 ammo out of a 10mm is as mentioned above by nicke10, if you are in a pinch. Take an extreme example...say I was on a hunting trip up in Alaska and stranded somewhere with no 10mm ammo, and the only thing I could scrounge up was some .40 I found in a cabin, it's good to know I could use the .40 ammo in my Glock 20.
I like the idea. A 9mm will rattle it's way out of a G23 but just doesn't cycle the action... yeah I know that one first hand
But I'm still a little leery of purposely feeding .40 through a G20. I will stick with the .40 cal in my G22 & G23 and leave the 10mm to well... 10mm Haha.
