As examples of what I said earlier about the upgrades on the Shadow 2 compared to my 75B, my 75B has the upgraded CZ Custom rear blind sight that hangs over the back plane of the slide a bit, and the stock ring hammer is a bit hard to thumb cock with the new extended rear sight. The Shadow 2 comes with the comp hammer that has the flat at the top so it is easy to cock that hammer with an extended rear sight. The Shadow 2 has the upswept beavertail that doesn’t bite the web of your shooting hand the way that the straight beavertail on my 75B can. The Shadow 2 has a checkered backstrap that I really like and which the 75B could surely use. These are all really great upgraded features on the Shadow 2 that IMHO are well worth the extra cost.
