Which caliber /version shield to get?

9mm

Although I like 45, my Shield is a 9mm CA version. Missing a critical hit with a 45 is the same as missing a critical hit with a 9, so I'd rather have one more in the mag.

The LCI doesn't bug me at all. Only mod is Trijicon HD's with yellow front, which I absolutely LOVE! Shot about 1000 rounds through it total, 530 of which were in a four day span. Mag springs kind of suck (not CA specific) - stiffer than I think they need to be and they wear out fast. Other than the slide closing on an empty magazine due to worn springs I haven't had any real malfunctions.
