OK... so your department allows you to carry a 1911 on duty, and is concerned with your second gun?....
Are you allowed to carry a firearm off duty?... What is/was the criteria for off duty carry guns?
I'm not getting something here.
Could you be confusing service revolver specs of days gone by?
I do remember one department (NYS Corrections) that for a while would only allow their officers to carry the same weapon off duty that they used as service revolvers. (S&W Model 10 4"bbl)
I think I'm missing something, or there us information being left out.
