I also use the Safariland 012 (I think that is the number) - great holster. I use it for my 6" open pistol, will use it on my 6" distinguish pistol, and have used it on my CZ 75 duty pistol. All you have to do is move one slide up/down a shaft. If you mark the shaft - it REALLY takes about 2 minutes to convert from one gun to the next. ken
Be careful though - this holster will NOT fit all pistols - check with Safariland.
