Rock Island 1911 Tactical. A LOT of gun (as in a good bit of gravity to it), so a pleasure to shoot. I'm super practical, so was hesitant to have yet another caliber to keep on hand, but it is not a huge problem. For me the 45ACP is purely a range gun - way too heavy for a lazy person like me to carry hunting, and too big to carry IWB. Fun gun for range, and I only keep enough ammo so I don't have to shop for it often.
Yeah, you can stack 5.56 and 9 high and deep for when the zombies come; but you don't need to keep all your ammo in that much of a supply. My wife was looking at a 380. She normally has zero interest in shooting, but I guess the 380 pistol looked small and manageable (the slide is a pleasure to work - espcially if you are used to a Shield). I was thinking, "Great...another thing to stock" but really she wouldn't be burning through more than 100-150 rounds at a time, so I settled on "If I get the pistol, I'll just get 1000 rounds of ammo and then not think about it for a while"
I have seen no reliabilty issues with the 1911. Yes, if you are used to breaking down a Glock, you will find the 1911 is a bit of a pain to work on. But it's something to play with - something different to bring and shoot.
