Thanks for that info on the Bersa cc. I've been thinking about one of those since it's what I see used in most of the ballistic test. Like the longer barrel too.
About the Zombie Max rounds: That was the first box of ammo I bought for my BG (it was all the store had) and I fired half of it to make sure it would feed. It's the same round as the critical defense except for the casing (nickel for the CD, brass for the zombie) and the color of the flex tip. The "Zombie Max" is just a marketing idea...and a good one at that. Gunsmith tells me that nickel casing(Critical Defense) is preferable because is reduces chances of feed jam when quick firing multiple rounds, also, it's easier to confirm the presense of a chambered round through the chambered round indicator.
