Wow, love these posts. The original poster is looking for suggestion on firearms that other people would recommend. People end of taking it as a chance to dismiss other people's post, just because of personal preference. Should be left up to the OP to review what other's have recommended as a firearm to suit his needs, and then take the chance to handle and shoot, which one he thinks is best upon other's suggestions.
For a modern firearm, I have personally shot S&W's and found that the Sigma series shot fine, but had an extended trigger pull and only operated in DAO. The weapon shot very well, and fed a variety of ammo, and the price tag for a new or like new one is well within the budget. The market has inflated prices quite a bit, but I have also fired from the S&W M&P line, both the .40 S&W and .45 ACP calibers. I preferred the 45 over the 40, and found the trigger pull more crisp than that of the Sigma line, it shot very well, the adjustable backstraps were a great feature offered to fit different size hands, and also has the option of adding Crimson Trace Laser grips. Not sure one of these could be found in your price range new from the store, however, could probably find a quality used one locally, or on a online auction site such as Gunbroker. Haven't fired much of the other pistols, but sure that they can offer you a great product to fit your requirements and you can afford either new or used.
Good luck in your search, and hope you post your new handgun, whatever it might be, when you purchase it.
