When I saw it, I just knew I had to have one. There has been a Blue'd MarkI that was sold to buy a Stainless Mark II bull barrel, that ended up being stolen in a home buglerly. The barrel is a little longer, and the clip release is moved up on the grip where a 1911 is located. The thing I like the most is the "loaded chamber indicator". You don't have to pull the slide back to see if it really has a bullet loaded.
