I say its a great choice. I'd recommend getting some actual trigger time on one before you make a purchase though. Try finding a range that can rent one to you. The USP .45 is an excellent firearm but everyone is different and you need to make sure it fits you well. As far as concealing it day to day, it is very doable. Before I got into Glocks, I carried a fullsized USP .45 every day. I'm not a big guy but it still concealed very well for me. A good holster goes a long way in what you can conceal. I'd recommend a Comptac M-tac. Very comfortable and made my USP disappear. Now I have another M-tac holster for my Glock 21, another big gun, which I can also conceal very well due to a good holster.
