Hello. Sig lists two different weights of these on their website. Click o one color and it's like 18 oz and another is over 30 oz. Are these full weight 1911's? Anybody have one? Do they work? Be fun to buy a 550 pack and have fun. Or do they needthe good stuff from CCI? Im looking at these pretty hard now. Haven't felt one in person though. Any advice would be appreciated. Even other brands.
