They are very cool old guns. 10-12 years back I had a 300 in .32 acp, a 400 and a 600, and somehow I ended up selling and trading all of them off. I would love to pick up another 300 and 600, but the prices around here have really gone up on them.

About 1/2 of the bad guys in the first couple seasons of Mission Impossible are armed with 400s.


I had always read that 400s would shoot just about anything that you fit into the magazine, but mine would only work with 9mm Largo and sometimes with .38 ACP.
