Well, I got tired of looking for a Mossberg 930 JM and bought the CZ on Saturday. I added a 2 round extension from my Remington 870 so it now holds a total of 7. I needed to do a little rigging to make it fit but it worked. Took it out today and ran two boxes of cheap, low brass Winchester dove loads thorough it without a single hick-up. This is my first tactical shotgun. I think it is a keeper. Do any of you have one? Now if I can find the Zombies.
