Are you sure you have the Shadow 2 and not the Custom 2?

This would be a good question to contact CZ USA about, not Bud's. I've seen several Shadow 2 models and none of them have had round hammers. Perhaps they ran out of hammers at the factory and had to use the standard one, but that's only a guess. I'm sure CZ would make it right for you if you contact them. 1-800-955-4486

The CZ Shadow 2 has always been made with the "race hammer" (the triangles one). The round hammer comes on the standard Shadow.

Hi Omar, The Cz shadow 2 comes with the Triangle hammer. Do you have the Dan Wesson model? This is the only model that comes rounded.

Hi Omar, since the community members here are not Buds employees, this will be a good question for Buds to answer at LiveChat (available from 9AM to 9PM 7 days a week), the "Blue Chat Now" bottom at the bottom right of the page at 9 EST in the morning, or phoning at (859) 368-0371 (available 9AM to 9PM EST Monday through Friday).
