I highly recommend the HK45C. I watched auctions and forums for 2+ years to find a good deal on a used one. New ones are IMO way too expensive.
I've owned too many 1911's to mention, Kahrs (never again), Sig P220 Carry, XD's and Glocks. The reliability, accuracy and ergonomics (in that order) of this little HK are stellar. YMMV....
