Earlier this year I purchased a new CZ75B "military" for $329. I just bought one of the new SA single action versions for $379, and there are some interesting differences. The thumb safety is ambidextrous and has been re-designed. It is now more positive, less likely to accidently come off, and it has been redesigned to be more like a 1911 safety, flatter and more positive when thumbing off. The beavertail has been reshaped, and allows a higher and more comfortable grip. A new hammer allows for the upswept beavertaiil. It is surprising how much better the grip feels. The slide also does not narrow at the final inch or so at the muzzle end, it now has some extra mass.
