I made mine a G29 for a little more packability, since I'm used to a 3" 1911. I'm spending much more time up north at my new place than I am at my previous home, so I opted for what gives me greatest confidence with larger threats, namely the 10mm. Like someone else that previously posted, my load is a Double Tap 200 gr, a full-house load, but not in any way objectionable, and quite accurate in my personal gun. It's my EDC, while up here. The G20 would be even more pleasant to shoot, but it is simply too large for EDC, for me.

I am the weapon; my gun is a tool. It's regrettable that with some people those descriptors are reversed.
