When the FA-83 first came out they were considered safe with the hammer block, now they are considered unsafe with 5 loaded. I have carried 5 in mine a number of times especially in Grizzly/Brown bear country with a loaded pack of raw moose meat. If the FA-83 is dropped from about 3 or more feet and the gun falls on the hammer on a hard surface it can break the hammer block and fire. This has happen to at least3 people that I know of.

The FA-83 is in no way as safe as a transfer bar system when fully loaded
4 in the cylinder is by far the safest way to carry a Freedom-83
