What is a "no-lock" revolver?
How does it differ from its opposite style?
Thanks in advance for a little schooling.
1) with an internal lock which has a small key with which you can lock the trigger mechanism
2) without the internal lock (as in most revolvers)
I was guided toward the "no-lock" as many purists feel it is just another thing to foul up the wonderful simpleness and reliability of revolvers.
