Large (some makers are now using small) pistol I have a conversion barrel to 9mm coming soon. No thanks.I love my Colt super and I've treated it like a Glock that gets treated like a lawn mower. The extractor and ejector have to be fussed over, and it takes time, money, and effort to determine which magazines and ammo work best in a particular gun. With the 9mm guns, even though I generally had good luck with them I always felt like I was one round away from a malfunction of some kind. Of course a couple of them see a lot higher volume of rounds than the others, but even so they just run. I currently own eight Colts in 45 and 38 Super and none of them have ever malfunctioned. And for a smaller cartridge, the 38 Super tends to run without much drama. I shoot the 45s better and they just work. I've gone down the 9mm 1911 road a few times and finally determined it's just not for me. Because a 9mm 1911 that runs and shoots accurately is a terrific handgun to shoot and carry, especially in the Lightweight Commander configuration.
