The subcompact .45 G36 and 30 are pretty much the same size as the compact .40 G23. More rounds for you with the .40, but since you're a wheelgunner I'm guessing you're not firepower-crazy so its all good. I find the .45 kicks easier for me, kind of a slow push compared to the sharp rap of the .40. Some are bothered enough by this to switch calibers, so try before you buy if possible.

1911-wise, there are a lot to choose from, and the compact officer's model size guns are about the same size as the Glocks you are eyeing. Most all the 1911 makers make a version, but the one that looks most interesting to me right now is Springfield's EMP. I don't mind 9mm for my compacts but they make a .40 version that would appeal to you. With it's slimmed down (fore AND aft) grip frame it would be just the ticket for smaller hands.

For other makers, someone already suggested Kahr, and I like their compact offerings. They feel good in the hand and are easy to pack. I think they make some of the smallest guns for the serious calibers. They have compact .45s and .40s in steel and polymer-framed versions.

The Walther PPS is looking like a contender in the compact gun crowd, but I don't know if they make em bigger than 9mm. About the same size as a PPK/S.

Good luck finding the right choice for you!
