I started in Law Enforcement with the Harris Co TX SO in the early 80’s. A few guys carried S&W .41 mag revolvers usually with the 210gr lead semi wadcutter “LE” load at 950fps.
I believe that the .44 load you are describing is the “mid-range” load that was a 240gr lead semi wadcutter at @1,000fps if memory serves they were bad to lead the bore. I carried a 4” M-29 for a year or more loaded with Speer 200gr JHP factory ammo. It was a bit “blasty”, but I also had two spare speedloaders of Remington’s 240gr jacked soft point ammo in the door pocket in case something really needed a hole punched thru it, the joys of excess testosterone and youth!
