WellI could go into a ton of different things, but I have learned that it is all personal preference. One thing that this has that a 191 does not is the constant trigger pull. For instane. If I have a round chambered, the hammer is automatically cocked internally, on the outside it is down, the trigger pull is the exact same for the first round all the way through. DA only. The trigger pull is ~5lbs, It is extremely comfortable, perfect size for CCW, (1911 is too big IMO) extremely accurate, looks so good you wanna kiss it, tested so strenuously that if you tried the tests that HK tried with any make 1911 they will explode. (do a search for the testing that HK does to their USP guns, you will truly be amazed. Quick easy takedown, reassembly, light. Those are just a few IMO of course for all you people who just Troll to argue.
