I started carrying with a Springfield XD.45. I have a Crossbreed Supertuck IWB holster for it. I am a small frame guy, only weigh 130 lbs soaking wet and I can conceal the XD just fine. My issue is the weight of it. At 14 rounds of .45 it can feel heavy on the hip especially when wearing a pair of shorts. So I got a Kimber Ultra Carry II .45 for Christmas. It is considerably smaller and 1/2 pound lighter. The only drawback would be the capacity is 7 + 1 so its cut in half from the XD. I really do like the 1911 though and may be trading the XD for a fullsize if I can get the right money.
