When I did private security I was allowed to furnish my own duty weapon. When I switched companies I was issued a S&W 64. When I became a Police Officer my first duty weapon was also a S&W 64. The security gun looked better but was in poor mechanical condition. Only 5 chambers would fire and the company would not get it fixed. The Police gun was in far better mechanical condition but looked beaten up. My only other issued duty handgun is a Beretta 92FS that I am still carrying.
