  1. Johnny Sprinkle –

    Much needed Mainspring to fix the hard trigger pull on the 1920 Colt New Service Revolver. The old spring was stretched out from the previous owner(s), and this was the right fix. Trigger pull with the new main spring is Double Action: 8.5 Lbs. and Single Action are 3.5 Lbs.

  2. Johnny Sprinkle –

    This was an excellent replacement for the original main spring on a 1922 Colt Army Special. The original main spring looked like it had been stretched out making for a hard trigger pull. The replacement main spring from Jack First gun parts was a quick fix and the trigger pull is nice and smooth now, thank you Jack First for having the parts available!
