The second version is blued steel and hopefully an option for a nickel finish. Again a great gun which can be carries and used. As of right now, 32 ACP is the only caliber available, but I think a 380 version may follow at some point. My take, although controversial, is that practically speaking there is no discernible difference between the two.
