[Double Tap]

Glock or Kimber, whatever your choice, it will be a good one. SIG's are great if you like double action guns, I don't. 45ACP is a good choice in a small carry gun, you don't loose much in velocity since it is a low pressure round to start with.

The polygonal rifling of the Glock achieves slightly higher velocities out of short barrels than conventional rifling. However, they lead up with cast bullets. Glocks are real workhorse guns. 1911 designs are also excellant. Both have ready spare parts availability and a huge market base. Something to consider when free trade is restricted. Glocks and 1911s and to some extant Berettas will be kept maintained easier than less common designs. Plenty of aftermarket support that S&W, taurus, Sig, HK and others do not have. BTW, HK USPs are also excellant high quality handguns.
