I am not necessarily in a big hurry. Of the ones mentioned the FN45, XD45 Tactical, and the CZ 97 look most interesting. The 15 rounds in the FN really appeals to me, I think. I will take my time and look at anything interesting and shoot if possible. Also the M&P 45 looks interesting. The HK may be a bit on the high end of my budget, but if I see one and it grabs me I may grab it back.
I may get a chance to see the new Sig 227 before I buy. Like I said, I am not in a hurry. I have bought too many guns without enough research. I'll take my time. I think.
