Your question is a tough one because there is no RIGHT answer to it. There are alot of factors that go into what is the proper handgun for each individual for concealed carry. One of my first suggestions is to either find a range that has rental guns for you to try, or if there is none around you that have rentals, go to the range where you currently shoot your Import Sports/Llama and talk to guys about what they carry and some may even let you shoot their guns. What is important is what feels good in YOUR hands, and if you can shoot it well. My second suggestion is for you not to overspend you budget on the gun alone. If you are going to a different caliber from your current .45acp, make sure you have enough money to purchase plenty of ammo to practice with. You would be surprised how many guys go and buy a gun, buy one box of ammo and load one magazine out of that box, load the gun and carry it :shock:
Other factors to consider is your size, planned mode of carry, and your normal mode of dress. When properly attired. I can easily carry a full sized 1911 in a IWB (inside the waistband) holster. During the summer when it is hot, I am known and prone to just be carrying a Kel Tec P32 w/pocket slipper laser in my back pocket.
Good luck in finding what you desire, and if you have any questions on specific handguns, feel free to post them either here or in the Handguns forum.
