I was having the same decision to make as you. I just bought a Taurus PT709 which is a 9mm last Thursday. I ran a couple of clips through it on Saturday and I think I made a good decision. I think it is classified as a sub compact, it has a stainless slide, holds 7 + 1, paid $ 359 for it. I used to have a Sig Sauer 220 45 cal but it was too big for me to conceal easily. The reason I went with a 9mm instead of a .380 is because the 9mm shells are cheaper and easier to find. I would recommend you check one of these out.
