Today I had some time to kill so I decided to stop buy my local shop just look around. As soon as I got there I spotted a gun I have been looking to buy since the mid 90's. A model 64 NY-1 in what appears to me to be great shape. I didn't even haggle I just whipped out the plastic. I am curious as to what was the duty load that NYPD used for these? I am assuming thats what the sight are regulated for. Any idea where I could get a holster for this, preferably something period correct. Any help or information is greatly appreciated.
